Features
Showing features for cross-link.
Type | ID | Position(s) | Description | |||
---|---|---|---|---|---|---|
Cross-link | 219↔245 | Tryptophyl-tyrosyl-methioninium (Tyr-Met) (with Trp-96) | ||||
Sequence: YVNPEGPGGNPDPVAAAKDIRETFARM |
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.
