Figure 2: HELFIT analyses of LRR domains. (A) Four helix parameters directly calculated by HELFIT in BRI1 with n=25; (B) Eight representativespig RI, Skp2, InlA, InlJ, YopM, FLS2, LINGO-1, and BACCAC_03700-of each class of LRRs. Black circles indicate the first unit. In panel B, six numerical values for each protein are in order from top to bottom: the repeat number n, the helix pitch P [Å], the rise per repeat unit Δz [Å], the rotation per repeat unit ΔΦ [o], the number of repeat units per turn N [units/repeat], and the helix radius R [Å]. Left and right figures of each protein indicate side views and views along the axes of a helix, respectively. In the side views the direction of helix axis is in the direction of the arrows. In the along views the cross signs show that it is in a downward direction and also the dots show that it is in a upward direction.
