The complete DNA sequence of VV revealed the presence of two potential proteinases, the products of the I7L andG1L open reading frames [9]. The first, I7L, was originallyidentified ... and is the culmination of two independent experiments. With the exception of wild type G1L, the E120A mutant and, to alesser extent the E35A mutant, none of the other mutantswere capable of complimenting...
