Antibodies directed toward the HIV-1 GP120 CD4 binding site with increased potency and breadth

Embodiments of the present invention are directed to compositions and methods for anti-HIV (anti-CD4 binding site) potent VRC01-like (PVL) antibodies targeted to gp120 having an amino acid substitution in the heavy chain at a residue in the anti-CD4 binding site PVL antibody that is equivalent to Phe43 in CD4 and an amino acid substitution in the light chain, these antibodies having improved potency and breadth
