Bifunctional enzyme CysN/CysC

Gene

cysNC

Organism
Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Protein inferred from homologyi

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. Sulfate adenylyltransferase subunit 2 (cysD), Bifunctional enzyme CysN/CysC (cysNC)
  2. Bifunctional enzyme CysN/CysC (cysNC), 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.

Caution

It is not obvious if the APS kinase domain is functional; the conserved active site serine (position 546) is replaced by an alanine. Furthermore P.aeruginosa seems to harbor a bona fide single domain APS kinase (CysC).Curated

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
