Identification
YMDB IDYMDB00918
Namel-Glutamic-gamma-semialdehyde
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionGlutamic-gamma-semialdehyde is the metabolic precursor for proline biosynthesis. The conversion from L-glutamate, an ATP- and NADPH- dependent reaction, is catalyzed by the enzyme delta-1-pyrroline-5-carboxylate synthetase (P5CS).
