Enzyme Information

1.8.1.5
2-oxopropyl-CoM reductase (carboxylating).
based on mapping to UniProt Q56839
2-mercaptoethanesulfonate + acetoacetate + NADP(+) = 2-(2-oxopropylthio)ethanesulfonate + CO(2) + NADPH.
-!- Also acts on thioethers longer in chain length on the oxo side, e.g. 2-oxobutyl-CoM, but this portion must be attached to CoM (2-mercaptoethanesulfonate); no CoM analogs will substitute. -!- Forms component II of a four-component enzyme system (comprising EC 4.4.1.23 (component I), EC 1.8.1.5 (component II), EC 1.1.1.268 (component III) and EC 1.1.1.269 (component IV)) that is involved in epoxyalkane carboxylation in Xanthobacter sp. strain Py2.
