Study

name:	A single-domain llama antibody potently inhibits the enzymatic activity of botulinum neurotoxin by binding to the non-catalytic alpha-exosite binding region.
description:	The epitope residues were calculated from [PDB: 3K3Q] as the antigen residues at 4Å atomic distance from the antibody. The solution Kd and binding kinectics of epitope specific Aa1 VHH bound to BoNT/A Lc were determined by flow fluorimetry in a KinExA instrument.
