2.6.1.127 |
| Accepted name: |
spermidine—8-amino-7-oxononanoate transaminase |
| Reaction: |
spermidine + 8-amino-7-oxononanoate = N-(3-aminopropyl)-4-aminobutanal + 7,8-diaminononanoate |
| Other name(s): |
BIO3-BIO1 (gene name) |
| Systematic name: |
spermidine:8-amino-7-oxononanoate aminotransferase |
| Comments: |
A pyridoxal 5′-phosphate enzyme. The enzyme, characterized from the plant Arabidopsis thaliana, differs from enzymes that catalyse a similar reaction by using spermidine as the amino group donor. The enzyme from Arabidopsis thaliana is bifunctional and also catalyses EC 6.3.3.3, dethiobiotin synthase. cf. EC 2.6.1.62, adenosylmethionine—8-amino-7-oxononanoate transaminase, and EC 2.6.1.105, lysine—8-amino-7-oxononanoate transaminase. |
