Superoxide dismutase [Cu-Zn] 1

Olea europaea (Common olive)
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli


Destroys radicals which are normally produced within the cells and which are toxic to biological systems. Probably involved in the protection against oxidative stress during pollen development.1 Publication

Catalytic activityi

2 superoxide + 2 H+ = O2 + H2O2.


Protein has several cofactor binding sites:
  • Cu cationBy similarityNote: Binds 1 copper ion per subunit.By similarity
  • Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity

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.
