CC ChEBI:CHEBI:64428; EC=2.8.1.7;
CC Evidence={ECO:0000256|ARBA:ARBA00001357,
CC ECO:0000256|RuleBase:RU004506};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|RuleBase:RU004504};
CC -!- SIMILARITY: Belongs to the class-V pyridoxal-phosphate-dependent
CC aminotransferase family. Csd subfamily. {ECO:0000256|ARBA:ARBA00010447,
