Features

Showing features for chain, cross-link.

TypeIDPosition(s)Description
ChainPRO_00003548311-726Catalase-peroxidase
Cross-link93↔216Tryptophyl-tyrosyl-methioninium (Trp-Tyr) (with M-242)
Cross-link216↔242Tryptophyl-tyrosyl-methioninium (Tyr-Met) (with W-93)

Post-translational modification

Formation of the three residue Trp-Tyr-Met cross-link is important for the catalase, but not the peroxidase activity of the enzyme.

Interaction

Subunit

Homodimer or homotetramer.
