RT "Induction of ResDE-dependent gene expression in Bacillus subtilis in
RT response to nitric oxide and nitrosative stress.";
RL J. Bacteriol. 184:1783-1787(2002).
CC -!- FUNCTION: Is involved in NO detoxification in an aerobic process,
CC termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and
CC NAD(P)H to convert NO to nitrate, which protects the bacterium from
CC various noxious nitrogen compounds. Therefore, plays a central role in
CC the inducible response to nitrosative stress (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=NADPH + 2 nitric oxide + 2 O2 = H(+) + NADP(+) + 2 nitrate;
CC Xref=Rhea:RHEA:19465, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,

CC -!- CATALYTIC ACTIVITY:
CC Reaction=NADH + 2 nitric oxide + 2 O2 = H(+) + NAD(+) + 2 nitrate;

CC ChEBI:CHEBI:57945; EC=1.14.12.17;
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344; Evidence={ECO:0000250};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
CC {ECO:0000250};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC Note=Binds 1 FAD per subunit. {ECO:0000250};
CC -!- INDUCTION: By nitric oxide, nitrite, and under oxygen-limited
CC conditions. {ECO:0000269|PubMed:11872732, ECO:0000269|PubMed:8682784}.
CC -!- DOMAIN: Consists of two distinct domains; an N-terminal heme-containing
CC oxygen-binding domain and a C-terminal reductase domain with binding
CC sites for FAD and NAD(P)H.
CC -!- SIMILARITY: Belongs to the globin family. Two-domain flavohemoproteins
CC subfamily. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the flavoprotein
CC pyridine nucleotide cytochrome reductase family. {ECO:0000305}.
