GMC oxidoreductases. A newly defined family of homologous proteins with diverse catalytic activities

J Mol Biol. 1992 Feb 5;223(3):811-4. doi: 10.1016/0022-2836(92)90992-s.

Abstract

Sequence comparison of Drosophila melanogaster glucose dehydrogenase, Escherichia coli choline dehydrogenase, Aspergillus niger glucose oxidase and Hansenula polymorpha methanol oxidase indicates that these four diverse flavoproteins are homologous, defining a new family of proteins named the GMC oxidoreductases. These enzymes contain a canonical ADP-binding beta alpha beta-fold close to their amino termini as found in other flavoenzymes. This domain is encoded by a single exon of the D. melanogaster glucose dehydrogenase gene.
