The carboxy terminal domain of the enzyme consists of amino acids 132–341 and it harbours the active site of the enzyme. The overall structure of this domain shares a great deal of structural resemblance to the catalytic domain of other enzymes of the same family such as λ Integrase and HP1 Integrase.
The terminal portion of the enzyme contains amino acids 132–341 and is responsible for the active site. The overall structure of this part shares a notable resemblance with the catalytic section of other enzymes in its class, including λ Integrase and HP1 Integrase.
