| Glossary: |
coenzyme M (CoM) = 2-sulfanylethane-1-sulfonate = 2-mercaptoethanesulfonate (deprecated) |
| Other name(s): |
2-(2-(S)-hydroxypropylthio)ethanesulfonate dehydrogenase; 2-[2-(S)-hydroxypropylthio]ethanesulfonate:NAD+ oxidoreductase |
| Systematic name: |
2-{[(2S)-2-hydroxypropyl]sulfanyl}ethanesulfonate:NAD+ oxidoreductase |
| Comments: |
The enzyme is highly specific for (2S)-2-hydroxyalkyl thioethers of CoM, in contrast to EC 1.1.1.268, 2-(R)-hydroxypropyl-CoM dehydrogenase, which is highly specific for the (R)-enantiomer. This enzyme forms component IV of a four-component enzyme system EC 4.4.1.23 (2-hydroxypropyl-CoM lyase; component I), EC 1.8.1.5 [2-oxopropyl-CoM reductase (carboxylating); component II], EC 1.1.1.268 [2-(R)-hydroxypropyl-CoM dehydrogenase; component III] and EC 1.1.1.269 [2-(S)-hydroxypropyl-CoM dehydrogenase; component IV].html">click here that is involved in epoxyalkane carboxylation in Xanthobacter sp. strain Py2. |
