The consensus sequences of putative C-terminal LRRs of NLRC5 and NLRC5-related proteins. Conserved residues are marked by pink background and „X” represents any residue. Synonymous amino acids: L, I and V; S and T; E, D, Q and N; R and K. Most frequent amino acids are shown within or under the consensus lines. Two typical types of LRRs are represented by A and B in case of RI and by 1 and 2 in case of NLRC5. aConsensus pattern of LRR proteins belonging to RI-like subfamily based on Bella et al. . „o” represents a nonpolar residue, „-” represents a possible insertion site, g represents Gly residue identical or conservatively substituted in its positions in more than 30% of sequences.
