[[1qbg]] is a 4 chain structure of [[Quinone reductase]] with sequence from [http://en.wikipedia.org/wiki/Homo_sapiens Homo sapiens]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=1QBG OCA].

== Function ==
[https://www.uniprot.org/uniprot/NQO1_HUMAN NQO1_HUMAN] The enzyme apparently serves as a quinone reductase in connection with conjugation reactions of hydroquinons involved in detoxification pathways as well as in biosynthetic processes such as the vitamin K-dependent gamma-carboxylation of glutamate residues in prothrombin synthesis.
