Enzyme Information
| 1.1.2.7 |
Methanol dehydrogenase (cytochrome c).
based on mapping to UniProt P14775
A primary alcohol + 2 cytochrome c(L) = an aldehyde + 2 reduced cytochrome c(L) + 2 H(+).
-!- A periplasmic quinoprotein alcohol dehydrogenase that only occurs in methylotrophic bacteria. -!- It uses the novel specific cytochrome c(L) as acceptor. -!- Acts on a wide range of primary alcohols, including ethanol, duodecanol, chloroethanol, cinnamyl alcohol, and also formaldehyde. -!- Activity is stimulated by ammonia or methylamine. -!- It is usually assayed with phenazine methosulfate. -!- Like all other quinoprotein alcohol dehydrogenases it has an 8-bladed 'propeller' structure, a calcium ion bound to the PQQ in the active site and an unusual disulfide ring structure in close proximity to the PQQ. -!- It differs from EC 1.1.2.8, alcohol dehydrogenase (cytochrome c), in having a high affinity for methanol and in having a second essential small subunit (no known function). -!- Formerly EC 1.1.99.8.
