|
|
|
|
|
||
| UniProt code: Q3JNW6. |
|
||
| Organism: | |
Burkholderia pseudomallei (strain 1710b). |
| Taxonomy: | |
Bacteria; Proteobacteria; Betaproteobacteria; Burkholderiales; Burkholderiaceae; Burkholderia; pseudomallei group. |
|
||
|
||
| Function: | |
Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity. {ECO:0000255|HAMAP-Rule:MF_01961}. |
|
||
| Catalytic activity: | |
Reaction=AH2 + H2O2 = A + 2 H2O; Xref=Rhea:RHEA:30275, ChEBI:CHEBI:13193, ChEBI:CHEBI:15377, ChEBI:CHEBI:16240, ChEBI:CHEBI:17499; EC=1.11.1.21; Evidence={ECO:0000255|HAMAP- Rule:MF_01961}; |
| Catalytic activity: | |
Reaction=2 H2O2 = 2 H2O + O2; Xref=Rhea:RHEA:20309, ChEBI:CHEBI:15377, ChEBI:CHEBI:15379, ChEBI:CHEBI:16240; EC=1.11.1.21; Evidence={ECO:0000255|HAMAP-Rule:MF_01961}; |
| Cofactor: | |
Name=heme b; Xref=ChEBI:CHEBI:60344; Evidence={ECO:0000255|HAMAP-Rule:MF_01961}; Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per dimer. {ECO:0000255|HAMAP-Rule:MF_01961}; |
| Subunit: | |
Homodimer or homotetramer. {ECO:0000255|HAMAP-Rule:MF_01961}. |
| 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}. |
| Similarity: | |
Belongs to the peroxidase family. Peroxidase/catalase subfamily. {ECO:0000255|HAMAP-Rule:MF_01961}. |
