KEGG   ENZYME: 1.7.99.1Help
Entry
EC 1.7.99.1                 Enzyme                                 

Name
hydroxylamine reductase;
hydroxylamine (acceptor) reductase;
ammonia:(acceptor) oxidoreductase
Class
Oxidoreductases;
Acting on other nitrogenous compounds as donors;
With other acceptors
BRITE hierarchy
Sysname
ammonia:acceptor oxidoreductase
Reaction(IUBMB)
NH3 + H2O + acceptor = hydroxylamine + reduced acceptor [RN:R00284]
Reaction(KEGG)
Substrate
NH3 [CPD:C00014];
H2O [CPD:C00001];
acceptor [CPD:C00028]
Product
hydroxylamine [CPD:C00192];
reduced acceptor [CPD:C00030]
Comment
A flavoprotein. Reduced pyocyanine, methylene blue and flavins act as donors for the reduction of hydroxylamine. May be identical to EC 1.7.2.1, nitrite reductase (NO-forming).
Pathway
Nitrogen metabolism
Orthology
K05601  
hydroxylamine reductase
K15864
