Enzyme Information

2.6.1.105
Lysine--8-amino-7-oxononanoate transaminase.
based on mapping to UniProt P53555
L-lysine + 8-amino-7-oxononanoate = (S)-2-amino-6-oxohexanoate + 7,8- diaminononanoate.
-!- Participates in the pathway for biotin biosynthesis. -!- The enzyme from the bacterium Bacillus subtilis cannot use S-adenosyl-L-methionine as amino donor and catalyzes an alternative reaction for the conversion of 8-amino-7-oxononanoate to 7,8- diaminononanoate (cf. EC 2.6.1.62). -!- Formerly EC 2.6.1.n2.
