Nucleotide sequence of gene F of Bacillus phage Nf

The nucleotide sequence of Bacillus phage Nf gene F has been determined. The deduced amino acid sequence of gpF is very similar to that of gp4, the transcriptional activator of phage phi 29. Both proteins contain the consensus structure that is conserved for the DNA-protein interacting domain of DNA-binding proteins such as the repressor, Cro and CII proteins of phage lambda.
