Design and synthesis of heterotrimeric collagen peptides with a built-in cystine-knot - Models for collagen catabolism by matrix-metalloproteases
No full textOttl J, Battistuta R, Pieper M, et al. Design and synthesis of heterotrimeric collagen peptides with a built-in cystine-knot - Models for collagen catabolism by matrix-metalloproteases. FEBS LETTERS. 1996;398(1):31-36.A heterotrimeric collagen peptide was designed and synthesized which contains the collagenase cleavage site (P-4-P'(9/10)) of type I collagen linked to a C-terminal cystine-knot, and N-terminally extended with (Gly-Pro-Hyp)(5) triplets for stabilization of the triple-helical conformation, By employing a newly developed regioselective cysteine pairing strategy based exclusively on thiol disulfide exchange reactions, we succeeded in assembling in high yields and in a reproducible manner the triple-stranded cystine peptide, While the single chains showed no tendency to self-association into triple helices, the heterotrimer (alpha 1 alpha 2 alpha 1') was found to exhibit a typical collagen-like CD spectrum at room temperature and a melting temperature (T-m) of 33 degrees C, This triple-helical collagen-like peptide is cleaved by the full-length human neutrophil collagenase (MMP-8) at a single locus fully confirming the correct raster of the heterotrimer, Its digestion proceeds at rates markedly higher than that of a single alpha 1' chain, Tn contrast, opposite digestion rates were measured with the catalytic Phe(79)-MMP-8 domain of HNC. Moreover, the full-length enzyme exhibits K-m values of 5 mu M and 1 mM for the heterotrimer and the single alpha 1' chain, respectively, which compare well with those reported for collagen type I (similar to 1 mu M), gelatine (similar to 10 mu M) and for octapeptides of the cleavage sequence (greater than or equal to 1 mM), The high affinity of the MMP-8 for the triple-helical heterotrimer and the fast digestion of this collagenous peptide confirm the decisive role of the hemopexin domain in recognition and possibly, partial unfolding of collagen

Shoreline changes on Mustang Island and North Padre Island (Aransas Pass to Yarborough Pass): an analysis of historical changes of the Texas Gulf shoreline
No full textBureau Publication GC7701 - to purchase a print copy please go to: https://store.beg.utexas.edu/geologic-circulars/427-gc7701.htmlHistorical monitoring along Mustang and north Padre Islands records the nature and magnitude of changes in position of the shoreline and vegetation line and provides insight into the factors affecting those changes.
Documentation of changes is accomplished by the compilation of shoreline and vegetation line position from topographic maps, aerial photographs, and coastal charts of various vintages. Comparison of shoreline position based on topographic charts (dated 1860-82) and aerial photographs (taken in 1937, 1956-60, 1969-70, and 1974-75) indicates short-term changes of accretion and erosion along the Gulf shoreline between Aransas Pass and Yarborough Pass. Erosion produces a net loss in land, whereas accretion produces a net gain in land. Comparison of the vegetation line based on, the aforementioned aerial photographs indicates short-term cycles of retreat related to storms (primarily hurricanes) and recovery during intervening years of low storm incidence.
Long-term trend or direction of shoreline changes averaged over the 115-year time period of this study indicates that Mustang Island has experienced net erosion with two exceptions. Net accretion adjacent to Aransas Pass, which decreased from 1,600 feet near the south jetty to 350 feet about 2 miles south of the pass, was caused principally by inlet migration and concomitant outbuilding of the north end of the island prior to jetty construction in 1889. Net accretion also occurred about 1.5 miles north of the Nueces/Kleberg county line attendant with the infilling of Packery Channel. The remainder of Mustang Island recorded net erosion ranging from 75 to 350 feet and averaging 225 feet. Net rates of change, however, were low along Mustang Island except where net accretion ranged from approximately 3 feet per year to 14 feet per year. Net erosion on the island ranged from less than 1 foot per year to 3.8 feet per year and averaged 2.0 feet per year.
Net changes on north Padre Island were predominantly accretionary; however, net erosion was recorded from Packery Channel southward for a distance of about 7 miles. Minimum net erosion was 50 feet, whereas maximum net erosion was 500 feet, and average net erosion was 220 feet. The shoreline from 6.5 to 9 miles north of the Kleberg/Kenedy county line experienced only minor net changes of 25 feet or less. The remaining shoreline of north Padre Island experienced net accretion ranging from less than 10 feet to 275 feet; net accretion, which increased southward along the island, averaged 140 feet. Net rates of change were also low along north Padre Island. Net erosion ranged from less than 1 foot to 5.4 feet per year and averaged 2.0 feet per year. Similarly, net accretion varied from less than 1 foot to 3.0 feet and averaged 1.5 feet per year. Because of limitations imposed by the technique used, rates of change are subordinate to trends or direction of change. Furthermore, values determined for long-term net changes should be used in context. The values for rates of net change are adequate for describing long-term trends; however, rates of short-term changes may be of greater magnitude than rates of long-term changes, particularly in areas where both accretion and erosion have occurred.
Major and minor factors affecting shoreline changes include: (1) climate, (2) storm frequency and intensity, (3) local and eustatic sea-level conditions, (4) sediment budget, and (5) human activities. The major factors affecting shoreline changes along the Texas Coast, including Mustang and north Padre Islands, are relative sea-level conditions, compactional subsidence, and changes in sediment supply. Changes in position of the vegetation line are primarily related to storms.
Studies indicate that changes in shoreline and vegetation line on Mustang and north Padre Islands are largely the result of natural processes, perhaps expedited by man's activities. A basic comprehension of these physical processes and their effects is requisite to avoid or minimize physical and economic losses associated with development and use of the coast.Bureau of Economic GeologyUT Librarie
Shoreline changes on Brazos Island and South Padre Island (Mansfield Channel to mouth of the Rio Grande): an analysis of historical changes of the Texas Gulf shoreline
No full textBureau Publication GC7502 - to purchase a print copy please go to: https://store.beg.utexas.edu/geologic-circulars/412-gc7502.htmlHistorical monitoring along Brazos and south Padre Islands records the nature and magnitude of changes in position of the shoreline and vegetation line and provides insight into the factors affecting those changes. Documentation of changes is accomplished by the compilation of shoreline and vegetation line position from topographic maps, aerial photographs, and coastal charts of various vintages. Comparison of shoreline position based on topographic charts (dated 1854, 1867, 1879-1880, 1917, 1934) and aerial photographs (taken in 1937, 1960, 1970, 1974) indicates short term changes of accretion and erosion along the beach between the mouth of the Rio Grande and Mansfield Channel. Erosion produces a net loss in land, whereas accretion produces a net gain in land. Comparison of the vegetation line based on the aforementioned aerial photographs indicates short term cycles of erosion related to storms (primarily hurricanes) and recovery during intervening years of low storm incidence. Long-term trend or direction of shoreline changes averaged over the 120-year time period of this study indicates net erosion for south Padre Island; maximum net erosion for this segment was 1,400 feet or approximately 13.1 feet per year. Minimum net erosion, in proximity to the north jetty at Brazos Santiago Pass, was 75 feet or less than 1 foot per year. The shoreline at the southern tip of south Padre Island has undergone accretion since construction of the jetties in 1935. The long-term shoreline trend of Brazos Island has been one of accretion; however, this is attributed to moderate and extreme accretion between 1854 and 1937. After this period, shoreline changes were short-term erosional and accretionary cycles. Because of limitations imposed by the technique used, rates of change are subordinate to t rends or direction of change. Furthermore, values determined for long-term net changes should be used in context. The values for rates of net change are adequate for describing long-term trends; however, rates of short term change may be of greater magnitude than rates of long-term changes, particularly in areas where both accretion and erosion have occurred. Major and minor factors affecting shoreline changes include: (1) climate, (2) storm frequency and intensity, (3) local and eustatic sea-level conditions, (4) sediment budget, and (5) human activities. The major factors affecting shoreline changes along the Texas Coast, including Brazos and south Padre Islands, are relative sea-level rise, compactional subsidence, and a deficit in sediment supply. Changes in position of the vegetation line are primarily related to storms. Studies indicate that changes in shoreline and vegetation line on Brazos and south Padre Islands are largely the result of natural processes, perhaps expedited by man's activities. The apparent effect of Falcon Dam upon the discharge of water and suspended sediment of the Rio Grande is marked, and the entrapment of sediment by the south jetties at Brazos Santiago Pass and Mansfield Channel is obvious. Structures that retard or eliminate sediment transport add to the sediment deficit already present in the littoral drift system. A basic comprehension of these physical processes and their effects is requisite to avoid or minimize physical and economic losses associated with development and use of the coast.Bureau of Economic GeologyUT Librarie
