pfam11534: HTHP (This model is not part of the current CDD release)
Hexameric tyrosine-coordinated heme protein (HTHP)
HTHP is from the marine bacterium Silicibacter pomeroyi and has peroxidase and catalase activity. HTHP consists of six monomers which each binds a solvent accessible heme group and is stabilized by the interaction of three neighboring monomers. The heme iron is penta-coordinated with a tyrosine residue as proximal ligand.
