| Accepted name: |
tubulin N-terminal N-acetyltransferase NAT9 |
| Reaction: |
acetyl-CoA + an N-terminal-L-methionyl-[tubulin] = an N-terminal-Nα-acetyl-L-methionyl-[tubulin] + CoA |
| Other name(s): |
NAT9 (gene name); microtubule-associated N-acetyltransferase NAT9 |
| Systematic name: |
acetyl-CoA:N-terminal-Met-[tubulin] Met-Nα-acetyltransferase |
| Comments: |
The enzyme, characterized from the fruit fly (Drosophila melanogaster), acetylates the N-terminal of both α- and β-tubulin. The enzyme acts cotranslationally, and can't act on a preformed tubulin α/β heterodimer. |
