No full textIdentification of a phosphorylated form of phosphoenolpyruvate carboxykinase from the yeast Saccharomyces cerevisiae.
No full textA phosphoprotein of 65 kDa, as determined by SDS-gel electrophoresis, has been isolated from yeast crude extracts. This phospho form copurifies with phosphoenolpyruvate carboxykinase in the enzyme purification procedure worked out in our laboratory (Tortora, P., Hanozet, G.M. and Guerritore, A. (1985) Anal. Biochem. 144, 179-185). Moreover, both proteins bind strongly to 5'AMP-Sepharose 4B in the presence of Mn2+, whereas a substantially lower binding occurs if Mn2+ is replaced by Mg2+. This binding pattern is consistent with the well-known Mn2+-dependence of yeast phosphoenolpyruvate carboxykinase. These data suggest that the 65-kDa protein might be a phosphorylation product of the native enzyme. Furthermore, although the phospho form is not immunoprecipitated by anti-phosphoenolpyruvate carboxykinase antibodies, addition of Protein A-Sepharose CL-4B to crude extracts preincubated with the antibodies results in the binding to the resin of the phospho form, thus providing immunological evidence for its identification as a modified form of native enzyme. The same 65-kDa phosphoprotein is detectable in extracts from cells grown in the presence of [32P]Pi, as well as in cell extracts incubated with [gamma-32P]ATP. Moreover, digestion of the phosphoprotein with BrCN or with Staphylococcus aureus V8 proteinase, yields two and three fragments, respectively, which appear parallel to digestion products of phosphoenolpyruvate carboxykinase, again supporting the proposed identification. Finally, analysis of the phosphorylated amino acids in the 65-kDa protein shows that phosphoserine is the only labelled phosphoamino acid
High-Speed and Wide-Field Photometry with TORTORA
No full textWe present the photometric analysis of the extended sky fields observed by the TORTORA optical monitoring system. The technology involved in the TORTORA camera is based on the use of a fast TV-CCD matrix with an image intensifier. This approach can both significantly reduce the readout noise and shorten the focal length following to monitor relatively large sky regions with high temporal resolution and adequate detection limit. The performance of the system has been tested using the relative magnitudes of standard stars by means of long image sequences collected at different airmasses and at various intensities of the moon illumination. As expected from the previous laboratory measurements, artifact sources are negligible and do not affect the photometric results. The following analysis is based on a large sample of images acquired by the TORTORA instrument since July 2006
