title: Acetate assimilation by the fission yeast, Schizosaccharomyces pombe.
abstract: The fission yeast Schizosaccharomyces pombe utilizes acetate at subinhibitory concentrations in the presence of D-glucose. The nonionized form of acetate is preferentially utilized, oxidized to 14CO2, and assimilated into lipids and proteins. Acetyl CoA synthetase activity greatly increases in the yeast cells grown in media containing acetate. However, glyoxylate cycle enzymes are not detectable in Schizosaccharomyces pombe. [1-14C]Acetate is incorporated into stereols, sterol esters, neutral lipids, and phospholipids. Assimilation of [1-14C]acetate into the peptide structure of proteins was confirmed by a proteolytic digestion experiment.
