IntEnz Enzyme Nomenclature


Accepted name:
2-(R)-hydroxypropyl-CoM dehydrogenase
Other name:
2-(2-(R)-hydroxypropylthio)ethanesulfonate dehydrogenase
Systematic name:
2-[2-(R)-hydroxypropylthio]ethanesulfonate:NAD+ oxidoreductase



The enzyme is highly specific for (R)-2-hydroxyalkyl thioethers of CoM, in contrast to EC, 2-(S)-hydroxypropyl-CoM dehydrogenase, which is highly specific for the (S)-enantiomer. This enzyme forms component III of a four-component enzyme system {comprising EC (2-hydroxypropyl-CoM lyase; component I), EC [2-oxopropyl-CoM reductase (carboxylating); component II], EC [2-(R)-hydroxypropyl-CoM dehydrogenase; component III] and EC [2-(S)-hydroxypropyl-CoM dehydrogenase; component IV]} that is involved in epoxyalkane carboxylation in Xanthobacter sp. strain Py2.
