    Members of the structurally-related superfamily of enzymes that includes RNase H, RuvC resolvase, MuA transposase, and retroviral integrase require divalent cations for enzymatic activity. So far, cation positions are reported in the X-ray crystal structures of only two of these proteins, E. coli and human immunodeficiency virus 1 (HIV-1) RNase H. Details of the placement of metal ions in the active site of retroviral integrases are necessary for the understanding of the catalytic mechanism of these enzymes.
