Examples of annotated LRR proteins. (A) Proteins containing LRRs from predominantly one class. (B) Proteins containing LRRs from predominantly the S and T classes. (C) Proteins containing LRRs from multiple classes. (D) Examples of proteins illustrating the occurrence of irregular LRRs both at the ends of LRR chains as well as within them. (E) Clustering of LRR proteins using LRR classes. A larger “zoomable” version is shown in Fig. S3. Cluster descriptions illustrate certain predominant features observed among representative LRR protein members in the respective clusters, e.g., F-box cluster consists predominantly of LRR proteins that also contain the F-box domain, whereas the NLR cluster consists mostly of NLR family members.
