2.6.1.72
Description D-4-hydroxyphenylglycine aminotransferase
Alternative names D-phenylglycine aminotransferase
Catalyzed reaction D-4-hydroxyphenylglycine + 2-oxoglutarate = 4-hydroxyphenylglyoxylate + L-glutamate.
Cofactor Pyridoxal-phosphate.
The enzyme from Pseudomonas strutzeri accepts as amino group donor only D-4-hydroxyphenylglycine or D-phenylglycine, whereas 2-oxoglutarate is the exclusive amino group acceptor and is converted into L-glutamate.
PDB 2CY8;
