Sequence and structure of Malus leucine-rich repeat family receptor-like polypeptide. Predicted translation product of the MxdRLP1-1 allele cloned from cultivars ‘Malling 26’, ‘Malling 27’ and ‘Robusta 5’. A predicted signal peptide cleavage site is indicated by an inverted arrowhead, and the signal peptide is double underlined. Nine consensus (LXXLXXLXLXXNXXαGXαPXXαG, where α represents any hydrophobic amino acid substitution [105]) LRR elements are boxed; the tenth degenerate element is boxed with a dotted line. The two mutated alleles isolated from cultivar ‘G.41’ are shown in boxes above the corresponding sequence.
