RCL regions and disulfide variants in Pin-II type PIs. a Preference of amino acids at P1, P2 and P1’ residues in the RCL regions (b) Distribution of RCL sequences across solanaceous and non-solanaceous plants. Frequently occurring RCL are shown separately in (b’) (c) Cysteine content (number of cysteine residues per sequence) in Pin-II type PIs and IRDs (inset) (d) Major types of disulfide bond architectures in IRDs.
