Description |
Ustiloxin B synthase (4.2.1.-) |
Alternative names |
UstD (gene name) |
Catalyzed reaction |
L-aspartate + oxidized ustiloxin C = ustiloxin B + CO(2). |
Cofactor |
Pyridoxal phosphate. |
Comments |
Ustiloxins are post-translationally modified peptides (found in bacteria and fungi) that exhibit potent antimitotic activity and interfere with
microtubule assembly.
The UstD enzyme from Aspergillus flavus presumably catalyzes a beta-decarboxylation reaction on L-aspartate, followed by a substitution with the aldehyde form of ustiloxin C, to generate ustiloxin B. |
