PGLYRP2 and infection: Of them, type-A proteins were referred to as putative “LysM effectors” which might have a role in the infection process, type B proteins were homologous to chitinases, type C proteins were homologous to the carbohydrate-binding antiviral protein cyanovirin-N, type D proteins were predicted to be involved in chitin binding but their function is unknown, and type E proteins were putative N-acetylmuramoyl-L-alanine amidases (de Jonge and Thomma, 2009).
