Abstract
The DNA sequence preferences of the compound meso-tetra-(4-N-methyl(pyridyl) porphyrin and its nickel complex have been investigated by means of footprinting experiments on several DNA fragments, using DNAase I and micrococcal nuclease as footprinting agents. A complex pattern of both AT and GC-protected sites was found. Ligand-induced long-range conformational changes were inferred in several instances to be related to the observed large-scale blockages of enzymatic cutting.
