phosphoserine transaminase  M-CSA #424

A pyridoxal-phosphate-dependent enzyme. It catalyses the second step in the phosphorylated pathway of serine biosynthesis in Escherichia coli (the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine). It also catalyses the third step in the biosynthesis of the coenzyme pyridoxal 5'-phosphate in E. coli (the reversible conversion of 3-hydroxy-2-oxo-4-phosphonooxybutanoate to phosphohydroxythreonine).
