Pyrroloquinoline quinone-dependent pyranose dehydrogenase

UniProtKB accession:  A8P0V4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Pyrroloquinoline quinone (PPQ)-dependent oxidoreductase that catalyzes the oxidation of various sugars including L-galactose, L-gulose, D-talose, D-arabinose, D-lyxose, L-fucose and D-glucosone (PubMed:25121592, PubMed:25679509, PubMed:27338639). Shows significant activity toward the reverse-chair conformation of pyranoses (PubMed:25679509). Shows little or no activity toward abundant sugars such as D-glucose, D-fructose, cellobiose, as well L-xylose and L-glucose (PubMed:25121592, PubMed:25679509). This enzyme is able to direct electrical communication with electrodes, without artificial electron mediators, thus allowing direct electron transfer (DET)-type bioelectrocatalysis (PubMed:27338639). Exhibits binding affinity for insoluble cellulose (PubMed:25679509). PDH does not oxidize cello-oligosaccharides but is able to activate the C-1-oxidizing Neurospora crassa LPMO9F and the C-4-oxidizing Neurospora crassa LPMO9C thanks to the electron-tranfer activity of the cytochrome domain and the localization of PDH in the vicinity of the LPMO substrates by the CBM1 domain (PubMed:29602785).
