General Information | Comment | Organism |
---|---|---|
evolution | in plants, gene families encode multiple isoforms of ATP sulfurylase with varied expression patterns and organelle localization | Glycine max |
metabolism | the first enzymatic reaction in the sulfur assimilation pathway of plants is the non-reductive adenylation of sulfate catalysed by ATP sulfurylase to yield adenylyl sulfate, APS, and diphosphate. The enzyme also catalyzes the next step, producing ADP and 3'-phosphoadenylyl sulfate from ATP and adenylyl sulfate, cf. EC 2.7.1.25 | Glycine max |
physiological function | the sulfur assimilation pathway provides sulfide for a range of biosynthetic pathways that supply methionine, glutathione, ironsulfur clusters, vitamin cofactors such as biotin and thiamin, and multiple specialized metabolites such as glucosinolates | Glycine max |
