| Description | This entry includes quinohemoprotein amine dehydrogenase (also known as QHNDH) subunit gamma. QHNDH catalyses the oxidative deamination of various aliphatic primary amines so that they can be assimilated as energy, carbon, and nitrogen sources. This enzyme is composed of three nonidentical subunits, designated alpha, beta, and gamma on the basis of their molecular sizes.The gamma subunit, the smallest of the three, is buried inside the alpha subunit and it has a particularly unusual structure consisting mostly of featureless coils with a covalently bound quinone cofactor, cysteine tryptophylquinone (CTQ), derived from Trp and Cys residues, and three intra peptidyl thioether cross-links formed between Cys and Glu or Asp residues [ ]. These structural features of the gamma subunit clearly indicate that it must undergo multiple posttranslational modifications before it can form an active QHNDH complex with the alpha and beta subunits []. | Name | Quinohemoprotein amine dehydrogenase subunit gamma |
