Protein
Adenosylmethionine-8-amino-7-oxononanoate aminotransferase
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Catalyzes the 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 animotransferase known to utilize SAM as an amino donor.
Similarity
Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. BioA subfamily.
