integrase (IN_a), its inactive variant containing mutation in the active site
D64V (IN_in), and inactive variant with mutations conferring resistance to elvitegravir
H51Y,
E92Q,
S147G,
E157Q,
K160Q (IN_in_e3), all with Met-Gly dipeptide on the N-terminus (A); Schematic representation of the structure of the synthetic genes.
Discussion: For HIV-1 clade A, the main mutations of elvitegravir resistance are
H51Y,
E92Q,
S147G, along with
E157Q and a secondary nonpolymorphic mutation,
K160Q, highly infrequent in
