Structure of filamentous bacteriophage: isolation, characterization, and localization of the minor coat proteins and orientation of the DNA.
The minor coat proteins of the filamentous bacteriophage fl and fd have been isolated and characterized. The phage have approximately 5 copies each of the A protein (product of gene III) and  the D protein (product of gene VI). The phage also contains about 10 copies of the C protein. Preliminary evidence suggests that the "C protein" may actually be a mixture of proteins, the major component of which is the product of gene IX. The D protein is located near or at the A protein end of the phage, and the C protein is located in a region near or at the other end. The DNA appears to be oriented iun the virion such that the DNA which specifies the intergenic region is located close to the C protein end of the phage and that which codes for the gene III protein is located near the A and D protein end.
