The recently determined structures of the catalytic domains of HIV integrase, avian sarcoma virus integrase and the Mu transposase are strikingly similar to each other and also exhibit significant similarity to several nucleases. All these enzymes of cut polynucleotides, leaving 3'OH and 5'PO4 groups. The integrase and transposase also possess a strand-transfer activity that splices DNA. The structural similarities among members of this superfamily of polynucleotidyl transferases suggest that they share a similar mechanism of catalysis.
