Accepted name: butane monooxygenase (soluble)
Reaction: butane + NADH + H+ + O2 = butan-1-ol + NAD+ + H2O
Other name(s): sBMO; bmoBCDXYZ (gene names)
Systematic name: butane,NADH:oxygen oxidoreductase
Comments: The enzyme, characterized from the bacterium Thauera butanivorans, is similar to EC, methane monooxygenase (soluble), but has a very low activity with methane. It comprises three components - a carboxylate-bridged non-heme di-iron center-containing hydroxylase (made of three different subunits), a flavo-iron sulfur-containing NADH-oxidoreductase, and a small regulatory component protein. The enzyme can also act on other C3-C6 linear and branched aliphatic alkanes with lower activity.
