Accession: PA1779
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA1779
Status: annotated
Amino acids: 908
Structure source: AlphaFold

1.9.6.1

GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:1990204 Any protein complex that possesses oxidoreductase activity. GO:0051539 Binding to a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands. GO:0046872 Binding to a metal ion. GO:0043546 Binding to a molybdopterin cofactor (Moco), essential for the catalytic activity of some enzymes, e.g. sulfite oxidase, xanthine dehydrogenase, and aldehyde oxidase. The cofactor consists of a mononuclear molybdenum (Mo-molybdopterin) or tungsten ion (W-molybdopterin) coordinated by one or two molybdopterin ligands. GO:0050140 Catalysis of the reaction: 2 Fe(II)-[cytochrome] + nitrate + 2 H+ = 2 Fe(III)-[cytochrome] + nitrite + H2O.
