Reaction(KEGG)
R12925
Substrate
Cu+ [CPD:C22423];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
Cu2+ [CPD:C22424];
H2O [CPD:C00001]
Comment
The enzyme, characterized from the bacterium Escherichia coli, is involved in copper tolerance under aerobic conditions. The enzyme contains a substrate binding (type 1) copper site and a trinuclear copper center (consisting of type 2 and type 3 copper sites) in which oxygen binding and reduction takes place. It also contains a methionine rich region that can bind additional copper ions. In vitro, if the substrate binding site is occupied by copper(II), the enzyme can function as a laccase-type quinol oxidase (EC 1.10.3.2). However, in vivo this site is occupied by a copper(I) ion and the enzyme functions as a cuprous oxidase.
