General annotation (Comments)

Function

Catalyzes the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-phosphonooxybutanoate to phosphohydroxythreonine By similarity. HAMAP-Rule MF_00160 SAAS SAAS022278

Catalytic activity

4-phosphonooxy-L-threonine + 2-oxoglutarate = (3R)-3-hydroxy-2-oxo-4-phosphonooxybutanoate + L-glutamate. HAMAP-Rule MF_00160 SAAS SAAS022278

O-phospho-L-serine + 2-oxoglutarate = 3-phosphonooxypyruvate + L-glutamate. HAMAP-Rule MF_00160 SAAS SAAS022278

Cofactor
