Enzyme Information
| 6.3.3.3 |
Dethiobiotin synthase.
based on mapping to UniProt B0F481
ATP + 7,8-diaminononanoate + CO(2) = ADP + phosphate + dethiobiotin.
-!- CTP has half the activity of ATP.
|
| 2.6.1.62 |
Adenosylmethionine--8-amino-7-oxononanoate transaminase.
based on mapping to UniProt B0F481
S-adenosyl-L-methionine + 8-amino-7-oxononanoate = S-adenosyl-4- methylthio-2-oxobutanoate + 7,8-diaminononanoate.
-!- S-adenosylhomocysteine can also act as donor.
