The Structure of the Quinoprotein Alcohol Dehydrogenase of Acetobacter Aceti Modelled on That of Methanol Dehydrogenase From Methylobacterium Extorquens

Biochem J. 1995 Jun 1;308 ( Pt 2)(Pt 2):375-9. doi: 10.1042/bj3080375.


The 1.94 A structure of methanol dehydrogenase has been used to provide a model structure for part of a membrane quinohaemoprotein alcohol dehydrogenase. The basic superbarrel structure and the active-site region are retained, indicating essentially similar mechanisms of action, but there are considerable differences in the external loops, particularly those involved in formation of the shallow funnel leading to the active site.
