Amino acid sequence alignments of pepper CaPMEI1 with Nicotiana tabacum DC1.2 protein (accession no. BAA95794), A. thaliana ripening-related protein (accession no. BAA97200), A. thaliana invertase homolog (accession no. NP201267) and Pinus radiata pectinesterase homolog (accession no. T08112). The boxed amino acid sequences represent the pectin methylesterase inhibitor (PMEI) domain. The conserved cysteine residues are marked by asterisks and the shaded regions represent conserved amino acid residues
