Maeda, Kayo
RESUMO
The amino-acid sequence of the single-stranded DNA-binding protein of bacteriophage Pf1 and the nucleotide sequence of the corresponding gene have been determined. The protein has 144 amino acids and a molecular weight of 15 400; the gene consists of 435 nucleotides. The amino-acid sequence was determined by Edman degradation, carboxypeptidase A, B, and P digestion of intact protein and of peptides derived by chymotrypsin, Staphylococcus aureus V8 protease, and trypsin digestion. The nucleotide sequence was determined by the dideoxy method after random cloning of fragments of Pf1 DNA into M13. No sequence homology could be established between the amino-acid sequence of the DNA-binding protein of Pseudomonas aeruginosa-specific bacteriophage Pf1 and bacteriophage fd of Escherichia coli.
