KEGG   ENZYME: 1.7.6.1
Entry
EC 1.7.6.1                  Enzyme                                 
Name
nitrite dismutase;
Prolixin S;
Nitrophorin 7
Class
Oxidoreductases;
Acting on other nitrogenous compounds as donors;
With a nitrogenous group as acceptor
Sysname
nitrite:nitrite oxidoreductase
Reaction(IUBMB)
3 nitrite + 2 H+ = 2 nitric oxide + nitrate + H2O [RN:R09751]
Reaction(KEGG)
R09751
Substrate
nitrite [CPD:C00088];
H+ [CPD:C00080]
Product
nitric oxide [CPD:C00533];
nitrate [CPD:C00244];
H2O [CPD:C00001]
Comment
Contains ferriheme b. The enzyme is one of the nitrophorins from the salivary gland of the blood-feeding insect Rhodnius prolixus. Nitric oxide produced induces vasodilation after injection. Nitrophorins 2 and 4 can also catalyse this reaction.
