7 GO annotations of molecular function

Name Definition
4 iron, 4 sulfur cluster binding 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.
electron transfer activity Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient.
iron ion binding Binding to an iron (Fe) ion.
molybdenum ion binding Binding to a molybdenum ion (Mo).
molybdopterin cofactor binding 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.
nitrate reductase (cytochrome) activity Catalysis of the reaction: ferrocytochrome + nitrate = ferricytochrome + nitrite.
nitrate reductase activity Catalysis of the reaction: nitrite + acceptor = nitrate + reduced acceptor.

2 GO annotations of biological process

Name Definition
Mo-molybdopterin cofactor biosynthetic process The chemical reactions and pathways resulting in the formation of the Mo-molybdopterin cofactor, essential for the catalytic activity of some enzymes. The cofactor consists of a mononuclear molybdenum (Mo) ion coordinated by one or two molybdopterin ligands.
nitrate assimilation The nitrogen metabolic process that encompasses the uptake of nitrate from the environment and reduction to ammonia, and results in the incorporation of nitrogen derived from nitrate into cellular substances.
