Protein

Copper chaperone CopZ

Gene

copZ

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Chaperone that serves for the intracellular sequestration and transport of Cu+. Delivers Cu+ to the copper-transporting ATPase CopA.

Miscellaneous

The copZA operon is activated by CueR and indirectly repressed by YfmP.
Cu+ ion is always at least three-coordinated. Physiological thiol may be needed to complete the Cu+ coordination sphere in order to prevent homodimer (dead-end products) formation between 2 CopZ.

Similar proteinsi

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.
