	r-amine:pyruvate_aminotransferase
Description	(R)-amine:pyruvate aminotransferase (2.6.1.-)
Catalyzed reaction	(R)-2-amine + pyruvate = 2- oxo-compound + D-alanine
Cofactor	Pyridoxal-phosphate.
	A novel (R)-amine transaminase, which catalyzed (R)-enantioselective transamination of chiral amine, was purified to homogeneity from Arthrobacter sp. KNK168. The enzyme catalyzed transamination between amines and pyruvate stereo-specifically. The deduced amino acid sequence was found to be homologous to those of the aminotransferases belonging to fold class IV of pyridoxal-5'-phosphate-dependent enzymes, such as branched-chain amino acid aminotransferases.
