Evidence
|
Both the N300A and the K305A mutants exhibited a neutralization profile similar to that of V2 loop tyrosine mutants, with increased sensitivity to sCD4 and weakly neutralizing antibodies 412d and 447-52D, while conversely showing decreased sensitivity to the trimer-preferring bNAb PG9; in contrast, mutation of N302 or R304 did not significantly alter the neutralization profile (Fig. 4).
