The translated primary structure of the
polygalacturonase inhibiting protein 1 (
PGIP1). Single letter codes are used to present amino acids. A: signal peptide, B: N-terminal domain, C: leucine-rich repeat LRR domain, and D: C-terminal domain. Hydrophobic amino acids leucine (L) and isoleucine (I) are highlighted in orange and the LRR consensus sequence is highlighted in lime. The N-glycosylation sites (N-X-S/T) are highlighted in red, with the cleavage site (A-L-S) highlighted in pink. N- and C-terminal cysteine residues are highlighted in sea green. Sheet-B1, sheet-B2 and 310-helix are highlighted with grey, blue and pink background colours, respectively.
