Accepted name: pyridoxamine-phosphate transaminase

Reaction: pyridoxamine 5'-phosphate + 2-oxoglutarate = pyridoxal 5'-phosphate + D-glutamate

Other name(s): pyridoxamine phosphate aminotransferase; pyridoxamine 5'-phosphate-α-ketoglutarate transaminase; pyridoxamine 5'-phosphate transaminase

Systematic name: pyridoxamine-5'-phosphate:2-oxoglutarate aminotransferase (D-glutamate-forming)

Comments: Also acts, more slowly, on pyridoxamine.
