Description

AI-generatedUnreviewed
The sulfate adenylyltransferase subunit 2 family is involved in the first enzymatic step of the sulfur assimilation pathway. Members of this family form a complex with CysN, known as ATP sulfurylase (ATPS), which catalyzes the adenylation of sulfate to produce adenosine 5'-phosphosulfate (APS) and diphosphate. The reaction is characterized by the formation of a high-energy phosphoric-sulfuric acid anhydride bond, which is driven by GTP hydrolysis by CysN and ATP hydrolysis by the CysD subunit. This process is crucial for the biosynthesis of sulfur-containing compounds, which are vital for various cellular functions.
