Quinonprotein alcohol dehydrogenase-like <p>Quinoprotein alcohol dehydrogenases are a family of proteins found in methylotrophic or autotrophic bacteria. These quinoproteins use pyrroloquinoline quinone as their prosthetic group. There are three types of alcohol dehydrogenases: type I includes methanol dehydrogenase and ethanol dehydrogenase, type II includes soluble quinohaemoprotein with a C-terminal containing haem C, and type III includes quinoprotein alcohol dehydrogenase with a C-terminal cytochrome C domain [<cite idref="PUB00014164"/>]. These quinoproteins contain an 8-bladed beta-propeller motif, which is present in the N-terminal domain of quinoprotein alcohol dehydrogenase, ethanol dehydrogenase, and the heavy chain (alpha subunit) of methanol dehydrogenase (<db_xref db="EC" dbkey="1.1.99.8"/>) [<cite idref="PUB00014163"/>, <cite idref="PUB00014162"/>, <cite idref="PUB00014161"/>].</p>
