Location of the structural genes for glycoproteins gD and gE and for other polypeptides in the S component of herpes simplex virus type 1 DNA.
To map the structural genes for the gD and gE polypeptides and for other viral products encoded in the S component of herpes simplex virus type 1 DNA, we selected mRNAs capable of hybridizing to cloned viral DNA fragments and translated the mRNAs in vitro to determine which polypeptides were encoded therein. The gD and gE polypeptides were identified by immunoprecipitation with appropriate monoclonal and monospecific antibodies, whereas the other polypeptides were characterized only by their electrophoretic mobilities in polyacrylamide gels. We found that gD mRNA hybridized to a single SacI subfragment of BamHI fragment J, whereas gE mRNA hybridized to an adjacent SacI subfragment of BamHI fragment J and also to BamHI fragment X. These and other results permit the conclusion that the structural gene for gD is located between map coordinates 0.911 and 0.924, and the gene for gE is between map coordinates 0.924 and 0.951. We also found that mRNAs for polypeptides of 55,000, 42,000, 33,000, and 22,000 molecular weight hybridized to DNA fragments spanning the regions from map coordinates 0.911 to 0.924, 0.897 to 0.911, 0.939 to 0.965, and 0.939 to 0.965, respectively. Finally, in accord with the results of others, we found that mRNA for a 68,000-molecular-weight polypeptide hybridized to the two noncontiguous BamHI fragments N and Z, which share a reiterated DNA sequence.
