Interact With
Induction INDUCTION: Expression increases from exponential to early- and late-stationary phase. Induced by H(2)O(2). {ECO:0000269|PubMed:12724378}.
Subcellular Location
Modified Residue
Post Translational Modification PTM: Formation of the three residue Trp-Tyr-Met cross-link is important for the catalase, but not the peroxidase activity of the enzyme. {ECO:0000255|HAMAP-Rule:MF_01961}.
