Protein

Adenylyl-sulfate kinase

Gene

cysC

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the synthesis of activated sulfate.

Catalytic activityi

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

Pathwayi: hydrogen sulfide biosynthesis

This protein is involved in step 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. Sulfate adenylyltransferase subunit 1 (cysN), Sulfate adenylyltransferase subunit 2 (cysD)
  2. Adenylyl-sulfate kinase (cysC)
  3. 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.
