Figure 5. Leucine-Rich Repeats(A) Structure of a single
22-residue InlB LRR. Backbone carbons are gray; side chain
carbons of conserved or restricted residues are orange;
nitrogens and oxygens are blue and red, respectively. Hydrogen
bonds are shown as black dotted lines. The location of the β
strand and 3[10]-helix are shown for reference. Repeat positions
7 to 10 form a distorted type II (β[P]γ) turn, and repeat
positions 21 to 2 (of the following repeat) form a type I (αα)
turn.(B) Alignment of the seven and one-half LRRs of InlB
(residues 77–242). The consensus repeat sequence is shown
below and contains the most commonly occurring residue; the
“s” at position 17 denotes a small residue.
