Substitutions of residues 84 (A), 85 (B), 90 (C), 92 (D), and 101 (E) in FR3 as introduced during somatic hypermutation processes of IgG-encoding genes derived from 11 different germline genes. Structure (F) of an IGHV5-51-derived scFv (PDB: 4BUH) indicating the side chain atoms of residues 84 (cyan), 85 (dark blue) in close proximity to CDR1, and of residues 90 (magenta), 92 (orange), and 101 (red). CDR are shown in brown (CDR1), green (CDR2), and light blue (CDR3).
