Comments [?]

FUNCTIONWith CysD forms the ATP sulfurylase (ATPS) that catalyzes the adenylation of sulfate producing adenosine 5'-phosphosulfate (APS) and diphosphate, the first enzymatic step in sulfur assimilation pathway. APS synthesis involves the formation of a high-energy phosphoric- sulfuric acid anhydride bond driven by GTP hydrolysis by CysN coupled to ATP hydrolysis by CysD.
CATALYTIC ACTIVITY Reaction=ATP + H(+) + sulfate = adenosine 5'-phosphosulfate + diphosphate; Xref=Rhea:RHEA:18133, ChEBI:CHEBI:15378, ChEBI:CHEBI:16189, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:58243; EC=;
PATHWAYSulfur metabolism; hydrogen sulfide biosynthesis; sulfite from sulfate: step 1/3.
SUBUNITHeterodimer composed of CysD, the smaller subunit, and CysN.
SIMILARITYBelongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. CysN/NodQ subfamily.

Comments Problematic entry. N-terminal too short in MYCTU. If in a nodulating bacteria, has to be done manually because of the presence of both cysN and nodQ.
