The restriction endonuclease PvuII from Proteus vulgaris has been converted from its wild-type homodimeric form into the enzymatically active single-chain variant scPvuII by tandemly joining the two subunits through the peptide linker Gly-Ser-Gly-Gly. scPvuII, which is suitable for the development of programmed restriction endonucleases for highly specific DNA cleavage, was purified and crystallized. The crystals diffract to a resolution of 2.35 A and belong to space group P4(2), with unit-cell parameters a = b = 101.92, c = 100.28 A and two molecules per asymmetric unit. Phasing was successfully performed by molecular replacement.
