Cajanus cajan lectins (CCL) is a promising candidate molecules for the protection against sap sucking insect pests like Lipaphis erysimi (Kaltenbach). Legume lectin toxicity against hemipteran has been proven by various experiments. This study explains the insecticidal potential of CCL through molecular modeling and docking with receptor alanyl Aminopeptidase N from Acyrthosiphon pisum membrane. | In silico analysis and molecular docking studies of Cajanus cajan lectin against aminopeptidase-n receptor from Acyrthosiphon pisum
