RC STRAIN=MWYL1; RG US DOE Joint Genome Institute; RA Copeland A., Lucas S., Lapidus A., Barry K., Glavina del Rio T., Dalin E., RA Tice H., Pitluck S., Kiss H., Brettin T., Bruce D., Detter J.C., Han C., RA Schmutz J., Larimer F., Land M., Hauser L., Kyrpides N., Kim E., RA Johnston A.W.B., Todd J.D., Rogers R., Wexler M., Bond P.L., Li Y., RA Richardson P.; RT "Complete sequence of Marinomonas sp. MWYL1."; RL Submitted (JUN-2007) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Bifunctional enzyme with both catalase and broad-spectrum CC peroxidase activity. {ECO:0000255|HAMAP-Rule:MF_01961}. CC -!- CATALYTIC ACTIVITY: CC Reaction=AH2 + H2O2 = A + 2 H2O; Xref=Rhea:RHEA:30275, CC ChEBI:CHEBI:13193, ChEBI:CHEBI:15377, ChEBI:CHEBI:16240, CC ChEBI:CHEBI:17499; EC=1.11.1.21; Evidence={ECO:0000255|HAMAP- CC Rule:MF_01961}; CC -!- CATALYTIC ACTIVITY: CC Reaction=2 H2O2 = 2 H2O + O2; Xref=Rhea:RHEA:20309, ChEBI:CHEBI:15377, CC ChEBI:CHEBI:15379, ChEBI:CHEBI:16240; EC=1.11.1.21; CC Evidence={ECO:0000255|HAMAP-Rule:MF_01961}; CC -!- COFACTOR: CC Name=heme b; Xref=ChEBI:CHEBI:60344; CC Evidence={ECO:0000255|HAMAP-Rule:MF_01961}; CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per dimer. CC {ECO:0000255|HAMAP-Rule:MF_01961}; CC -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000255|HAMAP-Rule:MF_01961}. CC -!- PTM: Formation of the three residue Trp-Tyr-Met cross-link is important CC for the catalase, but not the peroxidase activity of the enzyme. CC {ECO:0000255|HAMAP-Rule:MF_01961}. CC -!- SIMILARITY: Belongs to the peroxidase family. Peroxidase/catalase CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01961}.
