Unique features of the β-link in the immunoglobulin fold. (a) Region of the main chain in the vicinity of the β-link in T-cell receptor Vα11 (PDB entry 1h5b; Machius et al., 2001): SCOPe domain d1h5bc_, family b.1.1.1. (b) Region of the main chain in the vicinity of the β-link in the FnIII tandem A77–A78 domain of titin (PDB entry 3lpw; Bucher et al., 2010): SCOPe domain d3lpwb1, family b.1.2.0. (c) Fold as in (a), but shown complete in ribbon representation. The β-link is coloured red, and the rest of the region shown in (a) is coloured cream. (d) Fold as in (b), but shown complete for a single repeat in ribbon representation. The colour scheme is as in (c). |
