Showing features for chain, cross-link.
Type | ID | Position(s) | Description | ||
---|---|---|---|---|---|
Chain | PRO_0000354815 | 1-721 | Catalase-peroxidase 1 | ||
Cross-link | 98↔223 | Tryptophyl-tyrosyl-methioninium (Trp-Tyr) (with M-249) | |||
Cross-link | 223↔249 | Tryptophyl-tyrosyl-methioninium (Tyr-Met) (with W-98) | |||
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.
Expression
Induction
Induced during exponential growth.
