Biology of triacylglycerol accumulation by Rhodococcus
No full textMembers of the genus Rhodococcus are specialist in the accumulation of triacylglycerols (TAG). Some of them can be considered oleaginous microorganisms since they are able to produce significant amounts of those lipids under certain conditions. In this context, R. opacus strain PD630 and R. jostii RHA1 became models among prokaryotes in this research area. The basic knowledge generated for rhodococci could be also extrapolated to related microorganisms with clinical importance, such as mycobacteria. The biosynthesis and accumulation of TAG by species of the genus Rhodococcus and other actinomycetes seems to be a process linked to the stationary growth phase or as a response to stress. The chemical structure of rhodococcal TAG can be controlled by the composition of the carbon source used. The biosynthesis and accumulation of novel TAG containing unusual components, such as aromatic and isoprenoid fatty acids, by members of Rhodococcus and related genera has been reported. The low specificity of wax ester synthase/diacylglycerol acyltransferase enzymes (WS/DGAT), which catalyze TAG biosynthesis in prokaryotes, may contribute to the high variability of TAG composition. The occurrence of genes coding for WS/DGAT enzymes is highly redundant in rhodococcal genomes. The enrichment of genes and enzymes involved in TAG metabolism in rhodococci suggest an important role of these lipids in the physiology of these microorganisms. Genomic, transcriptomic and proteomic data from TAG-accumulating rhodococci are now available and some genes coding for enzymes of the central metabolism, the Kennedy pathway, lipid transporter proteins, structural lipid inclusion bodies associated proteins, and transcriptional regulatory proteins have been identified and characterized. This article aims to summarize the most relevant achievements of basic research in this field, including the most recent knowledge emerged from studies on TAG accumulation by rhodococci.Fil: Alvarez, Hector Manuel.

Interview with Hector Olvera Alvarez, Ph.D., P.E.
No full textDr. Hector Olvera Alvarez is a Professor and Senior Associate Dean for Research in the OHSU School of Nursing. In this oral history, Gregory Bratman interviews Dr. Olvera Alvarez about his childhood in Mexico, his educational background in civil engineering and theology, and his research into the connection between stress, environment, economic status, and the effects these have on a patient’s health across their life span. Other notable topics include Dr. Olvera Alvarez’s lifelong struggle with intellectual insecurity, his promotion of meaningful science and scholarship over productivity, and his work helping undergraduate researchers develop more philosophical scientific thinking
Central metabolism of species of the genus Rhodococcus
No full textMetabolism of Rhodococcus has evolved for adapting to a wide range of nutritional conditions. This adaptation often involves the flexibility of the central metabolism, which usually provides energy and precursors for biosynthesis processes, either during growth or during non-replicative metabolically active periods. The pathways of central metabolism are almost identical across widely divergent organisms, which share essentially the same metabolic network. However, this network possesses species-specific components, which depends on the biology of rhodococci. The central metabolism of members of Rhodococcus genus in the context of their physiology is the main topic of this chapter. An overview of main pathways of the central metabolism and their link with other metabolic processes is given. Glycolytic pathways, gluconeogenesis, phosphoenolpyruvate-pyruvate-oxalacetate node, tricarboxylic acid cycle (TCA), glyoxylate pathway and some litoautotrophic pathways are included.Fil: Hernández, Martín Alejandro.
