HIV-1 integrase is composed of three domains: the N-terminal (residues 1-49), the core domain (residues 50-212) and the C-terminal domain (residues 213-288). The core domain is responsible for the catalytic activity of the enzyme. It contains three acidic residues, the D,D-35-E motif which plays a key role in catalysis. The N-terminal domain includes the conserved HHCC motif, which binds zinc. The C-terminal domain is less well conserved.
