- GenebioA
- StatusUniProtKB unreviewed (TrEMBL)
- Amino acids425 (go to sequence)
- Protein existenceInferred from homology
- Annotation score3/5
Function
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 aminotransferase known to utilize SAM as an amino donor.
Catalytic activity
- (8S)-8-amino-7-oxononanoate + S-adenosyl-L-methionine = S-adenosyl-4-methylsulfanyl-2-oxobutanoate + (7R,8S)-7,8-diammoniononanoate
Cofactor
Pathway
Cofactor biosynthesis; biotin biosynthesis; 7,8-diaminononanoate from 8-amino-7-oxononanoate (SAM route): step 1/1.
