Abstract: G48V,
L90M, and
G48V/
L90M exhibited successively less processing in vitro than the wild-type enzyme, and the purified enzymes were 220-, 20-, and 720-fold, respectively, less sensitive to Ro 31-8959.
Abstract: The reduced enzyme sensitivity correlated directly with the sensitivities of the matched recombinant viruses, in that individual mutations
L90M and
G48V conferred 2-fold and 4- to 6-fold increases in 50% inhibitory concentration, respectively, whereas
G48V/
L90M was 8 to 10 times less sensitive to Ro 31-8959.
