comments
The tertiary structure of the N-terminal domains of this enzyme has not been determined yet. Only the catalytic domain of integrase has been solved so far. However, this enzyme seems to be homologous to the structures of its homologue, Pol polyprotein from Moloney murine leukemia virus (M00135 in EzCatDB), except for its N-terminal protease domain.
This enzyme catalyzes two successive reactions, hydrolysis (called processing) and transfer (called joining) (see [3]).
Although manganese is annotated as the cofactor, other divalent metal such as magnesium, cadmium and zinc can act as the cofactor (see [2] & [3]). However, in the presence of zinc ions, the polynucleotidyl transfer reaction can be inhibited, whilst the endonucleolytic reaction (hydrolysis) can be catalyzed (see [3]).
