General Information | Comment | Organism |
---|---|---|
evolution | the enzyme belongs to the ammonia monooxygenase (AMO)/particulate methane monooxygenase (pMMO) superfamily, copper membrane-associated monooxygenases (CuMOs), which is a diverse group of membrane-bound enzymes. The Ny_amoB structure reveals that the fold of the N-terminal domain of the B subunit in the AMO/pMMO superfamily is very well conserved as is the presence of an N-terminal copper binding site | Candidatus Nitrosocaldus yellowstonensis |
additional information | the pMMO active site is believed to reside in the soluble N-terminal region of the pmoB subunit. Modeling and structure comparisons of the N-terminal domain of the B subunit in the AMO/pMMO superfamily | Candidatus Nitrosocaldus yellowstonensis |
physiological function | enzyme AMO converts ammonia to hydroxylamine in nitrifiers | Candidatus Nitrosocaldus yellowstonensis |
