CC -!- FUNCTION: Heme-binding protein able to scavenge peroxynitrite and to
CC protect free L-tyrosine against peroxynitrite-mediated nitration, by
CC acting as a peroxynitrite isomerase that converts peroxynitrite to
CC nitrate. Therefore, this protein likely plays a role in peroxynitrite
CC sensing and in the detoxification of reactive nitrogen and oxygen
CC species (RNS and ROS, respectively). Is able to bind nitric oxide (NO)
CC in vitro, but may act as a sensor of peroxynitrite levels in vivo.
CC {ECO:0000255|HAMAP-Rule:MF_01297}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=peroxynitrite = nitrate; Xref=Rhea:RHEA:63116,
CC ChEBI:CHEBI:17632, ChEBI:CHEBI:25941; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01297};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:63117;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01297};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01297};
CC Note=Binds 1 heme b group per subunit, that coordinates a highly
CC solvent-exposed Fe(III) atom. {ECO:0000255|HAMAP-Rule:MF_01297};
CC -!- PATHWAY: Nitrogen metabolism. {ECO:0000255|HAMAP-Rule:MF_01297}.
CC -!- SUBUNIT: Homodimer. {ECO:0000269|PubMed:17172346}.
CC -!- DOMAIN: Forms a 10-stranded antiparallel beta-barrel structure able to
CC accommodate a hydrophobic ligand in its interior. In fact, this fold
CC hosts the heme group, which is located in a wide surface cleft.
CC {ECO:0000255|HAMAP-Rule:MF_01297}.
CC -!- MISCELLANEOUS: Was identified as a high-confidence drug target.
CC -!- SIMILARITY: Belongs to the nitrobindin family. {ECO:0000255|HAMAP-
CC Rule:MF_01297}.
