α-Amylase Inhibitors from Ficus Sp. Seeds and Their Activities Towards Coleoptera Insect Pests
α-Amylase Inhibitors were isolated from Ficus sp. (Gameleira) seeds by acetone fractionation and Sephadex G-50. Two inhibitors (α-PPAI and α-ZSAI) were tested against α-amylases from coleopteran larvae. α-PPAI was active to α-amylases of Callosobruchus maculatus (52%) and Zabrotes subfasciatus (53%). α-ZSAI was strongly active to Z. subfasciatus (100%) of and Mimosestes mimosae (98%). The α-ZSAI is a glycoprotein of ∼50kDa with an IC50 value of 0.074 μg μl-1.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
