Sterol synergism in yeast.
Sterol synergism as previously observed [Dahl, C.E., Dahl, J.S. & Bloch, K. (1980) Biochemistry 19, 1462-1467] and defined as a greater-than-additive growth response to pairs of sterols by Mycoplasma capricolum [Dahl, J.S., Dahl, C.E. & Bloch, K. (1981) J. Biol. Chem. 256, 87-91] is now demonstrated in the yeast mutant GL7, which is auxotrophic for sterol and unsaturated fatty acid. Mutant cell...
متن کاملSterol Biosynthesis and Metabolism in Marine Invertebrates
The present state of knowledge on the ability of marine invertebrate animals to synthesise and metabolise sterols is reviewed. While animals from some phyla have a limited ability to synthesise sterols .a other groups of invertebrates are apparently incapable of sterol synthesis. It appears likely that much of the sterol of invertebrates originates from algae either in the plankton or living as...
متن کاملSterol composition in muscle and viscera of the marine bivalve Megangulus zyonoensis from coastal waters of Hokkaido, northern Japan.
Sterol composition in muscle and viscera tissues of the marine bivalve Megangulus zyonoensis was investigated. Among 13 different sterols identified by gas chromatography-mass spectrometry of their trimethylsilyl ether derivatives, cholesterol was the most abundant sterol, followed by 24-methylenecholesterol, in both muscle and viscera tissues. In this study, the proportion of brassicasterol, i...
متن کاملThe effect of changed sterol composition on the kinetics of mitochondrial membrane enzymes in the yeast Saccharomyces cerevisiae [proceedings].
The effect of sterols on the kinetics of membrane-bound enzymes was examined. Two strains of the yeast Saccharomyces cerevisiae were used for this purpose: the wild-type haploid strain, S288C, and the lipid auxotroph mutant Ole-3 (Resnick & Mortimer, 1966). The primary lesion in the Ole-3 mutant is the loss of 8-aminolaevulinate synthetase (EC 2.3.1.37) (Woods et al., 1975). Consequently, the m...
متن کاملMechanisms of sterol uptake and transport in yeast.
Sterols are essential lipid components of eukaryotic membranes. Here we summarize recent advances in understanding how sterols are transported between different membranes. Baker's yeast is a particularly attractive organism to dissect this lipid transport pathway, because cells can synthesize their own major sterol, ergosterol, in the membrane of the endoplasmic reticulum from where it is then ...
