Cloning, nucleotide sequence and high level expression of the gene coding for the connector protein of Bacillus subtilis phage phi 29.
The phi 29 DNA restriction fragment HindIII-D, shown to contain gene 10 coding for the connector protein, has been cloned in plasmid pPLc28 under the control of the pL promoter of phage lambda. After heat induction to inactivate the lambda repressor, a protein with the electrophoretic mobility of the connector protein p10 was synthesized, accounting for about 30% of the total Escherichia coli protein after 3 h of induction. The 2205 nucleotide-long sequence of the cloned HindIII-D fragment has been determined. The sequenced region has an ORF coding for a protein of Mr 35881 that was shown to correspond to the connector protein by determination of the amino-terminal sequence of purified protein p10. Features of the nucleotide sequence and the amino acid sequence of protein p10 are discussed.
