Abstract
Previous papers have reported that the syncytial mutant HSV-1(13)S11 carries three segregable syn mutations and exhibits its altered phenotype in four different cell lines i.e. HEp-2, VERO, BHK and HEL both at 34°C and 39°C. Those studies have shown that one of three syncytial loci, designated Syn 5, is located in the Bam HI Q fragment spanning map units 0.296-0.317 of the prototype arrangement. Recombinants obtained from marker transfer experiments with donor BamHI Q fragment, have shown that locus Syn 5 is able to induce cell-to-cell fusion in VERO, BHK and HEL but not in HEp-2 cells. In this paper we have characterized the syn mutant HSV-1(13)S11 with regard to plaque morphology, synthesis of viral polypeptides and glycoproteins, thymidine kinase activity and physical map position of locus Syn 5 on the genome. Pertinent to the syn phenotype, earlier papers claimed that two different polypeptides, thymidine kinase (TK) and glycoprotein H (gH), whose genes map in BamHI Q, may be respo...I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
