SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionPhosphoaspartate belongs to the class of organic compounds known as aspartic acid and derivatives. Aspartic acid and derivatives are compounds containing an aspartic acid or a derivative thereof resulting from reaction of aspartic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Phosphoaspartate is possibly soluble (in water) and a very strong basic compound (based on its pKa). Phosphoaspartate exists in both E. coli (prokaryote) and yeast (eukaryote).
