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 possibly modulating the transcriptional activity residing in the N-
CC terminal region. {ECO:0000250|UniProtKB:Q8WY91}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=peroxynitrite = nitrate; Xref=Rhea:RHEA:63116,
CC ChEBI:CHEBI:17632, ChEBI:CHEBI:25941;
CC Evidence={ECO:0000250|UniProtKB:Q8WY91};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:63117;
CC Evidence={ECO:0000250|UniProtKB:Q8WY91};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000250|UniProtKB:Q8WY91};
CC Note=Binds 1 heme b group per subunit, that coordinates a highly
CC solvent-exposed Fe(III) atom. {ECO:0000250|UniProtKB:Q8WY91};
CC -!- PATHWAY: Nitrogen metabolism. {ECO:0000250|UniProtKB:Q8WY91}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q8WY91}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q8WY91}. Nucleus
CC {ECO:0000250|UniProtKB:Q8WY91}. Note=Localizes mainly in the cytoplasm
CC and partially in the nucleus. {ECO:0000250|UniProtKB:Q8WY91}.
CC -!- DOMAIN: The C-terminal nitrobindin region coordinates a heme and bears
CC the isomerase activity. The N-terminal zinc finger domain likely binds
CC DNA and may be involved in transcriptional regulation.
CC {ECO:0000250|UniProtKB:Q8WY91}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the nitrobindin
CC family. {ECO:0000305}.
