... mechanism, it was proposed that the C-terminal 17 residues of the A domain of FnBPB form the latching peptide and play a similar role in the interaction of FnBPB with Fg. To test this hypothesis, ... objective of this project was to determine whether the A domain of FnBPB binds Fg by the same mecha- nism as the A domain of ClfA. A three-dimensional molecular...
