WebHuman cyclophilin B is a monomeric protein that contains two tryptophan residues, Trp104 and 128. Trp128-residue belongs to the binding site of cyclosporin A and is the homologous of Trp 121 in CyPA, while Trp104 residue belongs to the hydrophobic pocket. In the present work, we studied the dynamics of Trp residue(s) of cyclophilin B and of the CyPBw128A … WebNational Center for Biotechnology Information
