'''Methylamine utilisation protein'''. (MauG) is a 2 c type heme protein (in which the heme is covalently bound to the protein) which catalyses the post translational modification of tryptophan cryptophilquinone biosynthesis within methylamine dehydrogenase (MADH).  The catalysis process is a remote one involving hole hopping mechanism of electron transfer in which Top residues are reversibly oxidized<ref>PMID:24144526</ref>.  MauG catalyses the 6-electron oxidation of MADH using hydrogen peroxide or oxygen.

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
