Geometry of the junction in a β-sandwich at the position of a β-link. Illustrated is jelly-roll/β-sandwich SCOPe domain d2q1ma1 of glucocorticoid-induced TNF receptor ligand (PDB entry 2q1m; Chattopadhyay et al., 2007), SCOPe family b.22.1.1. (a) Ribbon plot of the domain. The β-strands of the two sheets are coloured salmon and light blue, the β-link is red and the connection made by the strand with the singleton is black. Other non-β-strand regions are coloured cream. (b) The backbone atoms of the two strands of the β-link are shown, together with the adjacent strand, in a plan view. (c) As (b) but in a side view, with constituent motifs of the β-link indicated to allow comparison with Fig. 1. |
