• Mutational nucleotide sequence changes by ultraviolet light (UV) in the gene for Escherichia ccli cAMP receptor protein (CRP) were analyzed. Transitions were most the frequent mutations and occurred at pyrimidine-pyrimidine sequences. Most transitions were GC to AT base changes at 3' cytosine of 5'-pyrimidinecytosine-3' sequences, supporting the concept that pyrimidine(6-4)pyrimidone, Pyr(6-4)Pyo, photoproduct is a principal pre-mutagenic lesion for transition mutations induced by UV. Transversion and frameshift mutations were also found.
