FAMILY

class-III pyridoxal-phosphate-dependent aminotransferase family

DESCRIPTION

Also known as BIOA_MYCTU, bioA. Catalyzes the reversible transfer of the alpha-amino group from S-adenosyl-L-methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to form 7, 8-diaminopelargonic acid (DAPA). It is the only aminotransferase known to utilize SAM as an amino donor (PubMed:20565114, PubMed:16984394). Can also use sinefungin but not S-adenosylhomocysteine as substrate (PubMed:20565114). Homotetramer (PubMed:16984394). Homodimer (PubMed:20565114).
