Known hematophagous arthropod peritrophic matrix peritrophins. Peritrophic matrix peritrophin classification according to their chitin-binding domains (CBDs). Peritrophin-A domain (PAD) is the most common type of CBD with six interspersed cysteine residues. Modified peritrophin-A domains (mPADs) have two additional cysteine residues. Peritrophin-C domain (PCD) contains 10 interspersed cysteine residues, and typically 121–122 amino acid residues long. Partial PCDs contain 67–70 amino acids. Type III carbohydrate binding domains (CBDIII) contains 10 interspersed cysteine residues, similar to PCD, this domain is typically 110–117 amino acid residues long. ^aMorlais and Severson, 2001; ^bShao et al., 2005; ^cShen and Jacobs-Lorena, 1998; ^dDinglasan et al., 2009; ^eDevenport et al., 2005; ^fDimopoulos et al., 1998; ^gHao and Aksoy, 2002; ^hRose et al., 2014; ⁱJochim et al., 2008; ^jRamalho-Ortigão et al., 2007; ^kNarasimhan et al., 2014.
