Abstract

The tsB5 isolate of herpes simplex virus type I (HSV-1) enters host cells more rapidly than does KOS, an independent isolate of HSV-1, and this rate-of-entry determinant is located between prototypic map coordinates 0.350 and 0.360 (1). The nucleotide sequence of strain tsB5 has now been determined between prototypic map coordinates 0.347 and 0.360. Comparison of the tsB5 sequence to the homologous KOS sequence revealed that the rate-of-entry difference between these two HSV-1 strains may be due to the single amino acid difference observed within these sequences (0.350 to 0.360). A cell fusion determinant in tsB5 is located between coordinates 0.345 and 0.355 and to the left of the rate-of-entry determinant (1). Nucleotide sequence analysis revealed a second amino acid difference between tsB5 and KOS at coordinate 0.349. The cell fusion determinant was tentatively assigned to this location.
