Cover: The calculated hydrodynamic outline of the ocr protein of bacteriophage T7 (gold outline) is superimposed upon a model of part of the DNA methyltransferase core of a type I DNA restriction enzyme (CPK colours) bound to its DNA target (green). Ocr is of the correct size and shape to fill the DNA binding groove of the enzyme and allows ocr to be a potent inhibitor of the type I restriction enzymes. For further details see the paper by Atanasiu et al. in this issue: [Nucleic Acids Res. (2001) 29, 3059-3068].
