Product Overview
High-quality enzyme products.
Well-established quality management system.
Reaction
(1) O-phospho-L-serine + 2-oxoglutarate = 3-phosphooxypyruvate + L-glutamate
(2) 4-phosphooxy-L-threonine + 2-oxoglutarate = (3R)-3-hydroxy-2-oxo-4-phosphooxybutanoate + L-glutamate
Systematic Name
O-phospho-L-serine:2-oxoglutarate aminotransferase
Function
A pyridoxal 5′-phosphate protein. This enzyme catalyses the second step in the phosphorylated pathway of serine biosynthesis and the third step in pyridoxal 5′-phosphate biosynthesis in the bacterium Escherichia coli. Pyridoxal 5′-phosphate is the cofactor for both activities and therefore seems to be involved in its own biosynthesis. Non-phosphorylated forms of serine and threonine are not substrates. The archaeal enzyme has a relaxed specificity and can act on L-cysteate and L-alanine as alternative substrates to O-phospho-L-serine.
