Post-translational modificationi

The Cys-48-SH group is the primary site of oxidation by H2O2, and the oxidized Cys-48 (probably Cys-SOH) rapidly reacts with Cys-171-SH of the other subunit to form an intermolecular disulfide. This disulfide is subsequently reduced by thioredoxin.

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.
