title: Construction and properties of a viable herpes simplex virus 1 recombinant lacking coding sequences of the alpha 47 gene.
abstract: The five alpha genes, alpha 0, alpha 4, alpha 22, alpha 27, and alpha 47, are the first set of herpes simplex virus 1 genes to be transcribed and expressed in productively infected cells. We report here the construction of a viral recombinant from which all of the coding sequences of the alpha 47 gene were deleted. In addition to the alpha 47 protein, infected cell lysates did not contain detectable amounts of two polypeptide bands with apparent molecular weights of 18,000 and 21,000 which could be specified by a gene whose regulatory domain and 5' transcribed noncoding sequences overlap with the coding sequences of the alpha 47 gene. The alpha 47- virus grew as well as the wild-type parent virus in Vero, baby hamster kidney, and Rat-1 cell lines.
