Abstract: The connector of bacteriophage phi 29 is required for prohead assembly, binds DNA, and drives DNA packaging into viral proheads. Limited proteolysis of the connector protein with endoproteinase Glu-C from Staphylococcus aureus V8 and chymotrypsin showed that a domain of the NH2-terminal region is involved in DNA binding and in the subsequent packaging into preformed proheads, but not in prohead assembly. Mutants in specific amino acids of the NH2-terminal domain, obtained by directed mutagenesis techniques, showed that the Ala1-Arg2-Lys3-Arg4 region of the connector is absolutely necessary for DNA packaging into the proheads as well as for efficient DNA binding.
