Protein

Bifunctional enzyme CysN/CysC

Gene

cysNC

Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

ATP sulfurylase may be the GTPase, regulating ATP sulfurylase activity.By similarity
APS kinase catalyzes the synthesis of activated sulfate.By similarity

Catalytic activityi

ATP + sulfate = diphosphate + adenylyl sulfate.
ATP + adenylyl sulfate = ADP + 3'-phosphoadenylyl sulfate.

Pathwayi: hydrogen sulfide biosynthesis

This protein is involved in step 1 and 2 of the subpathway that synthesizes sulfite from sulfate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Adenylyltransferase (cysN), Bifunctional enzyme CysN/CysC (cysNC), Sulfate adenylyltransferase subunit 2 (cysD), Sulfate adenylyltransferase subunit 2 (cysD)
  2. Adenylyltransferase (cysN), Bifunctional enzyme CysN/CysC (cysNC)
  3. Phosphoadenosine phosphosulfate reductase (cysH), Probable phosphoadenosine phosphosulfate reductase (cysH)
This subpathway is part of the pathway hydrogen sulfide biosynthesis, which is itself part of Sulfur metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes sulfite from sulfate, the pathway hydrogen sulfide biosynthesis and in Sulfur metabolism.
