Function

function

Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Features

Showing features for cross-link.

TypeIDPosition(s)Description
Cross-link233↔259Tryptophyl-tyrosyl-methioninium (Tyr-Met) (with Trp-110)

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.
