Xib, a gene recently reported to reside on the q28 region of the human X chromosome [Pergolizzi et al. (1996) Gene 168, 267-270], contains an open reading frame homologous to those of the DNase I family enzymes. The full open reading frame of this gene has been fused to the E. coli gene of the maltose binding protein and expressed in bacteria as a chimeric protein. The partially purified chimeric protein is enzymatically active. It introduces single and double stranded breaks into supercoiled DNA, at 30 degrees C in the absence of divalent cations and at a pH optimum of 5.2. To our knowledge this enzyme represents the first cloned human endonuclease with characteristics similar to those of acidic DNase II.
