Comments [?]

Function May be the GTPase, regulating ATP sulfurylase activity.
Catalytic activity RHEA:18133: ATP + H(+) + sulfate = adenosine 5'-phosphosulfate + diphosphate
EC 2.7.7.4
Pathway Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite from sulfate: step 1/3.
Subunit Heterodimer composed of CysD, the smaller subunit, and CysN.
Similarity Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. CysN/NodQ subfamily.

Size range 441-494 amino acids
Related rules None
Fusion Nter: None; Cter: MF_00065 (cysC)
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.
