Enzyme Information
| 1.14.13.225 |
F-actin monooxygenase.
based on mapping to UniProt Q8TDZ2
[F-actin]-L-methionine + NADPH + O(2) + H(+) = [F-actin]-L-methionine- (R)-S-oxide + NADP(+) + H(2)O.
-!- The enzyme, characterized from the fruit fly Drosophila melanogaster, is a multi-domain oxidoreductase that acts as an F-actin disassembly factor. -!- The enzyme selectively reduces two L-Met residues of F-actin, causing fragmentation of the filaments and preventing repolymerization. -!- Free methionine is not a substrate. -!- The reaction is stereospecific and generates the (R)-sulfoxide.
