Abstract: Several polymorphisms in RT: D123S, Q174K, D177E, T200A, V245Q, and PR: I13V, K20I, M36I, R41K, H69K, L89M were detected more frequently in non-B and recombinants than in B strains (P<0.01 to P<0.001).
Genetic variability of HIV-1 protease from Nigeria and correlation with protease inhibitors drug resistance.
Abstract: The protease amino acid consensus sequence of the Nigerian subtype A are in complete agreement with the consensus A differing from the USA subtype B consensus in 10 positions (L10V, I13V, K14R, I15V, K20I, M36I, R41K, P63L, H69K and L89M).
Catalytic efficiency and vitality of HIV-1 proteases from African viral subtypes.
Abstract: The A protease used in these studies differs in seven positions (I13V/E35D/M36I/R41K/R57K/H69K/L89M) in relation to the consensus B subtype protease.
