Abstract excerpt

An insect antifreeze protein, MpAFP698, from the desert beetle Microdera punctipennis, shares 77% similarity with TmTHP (YL-3) from Tenebrio molitor. The predicted tertiary structure for MpAFP698 was modeled as a regular A-helix with TCT motifs arrayed to form the putative ice-binding surface. This model was validated via site-directed mutagenesis. The results suggest that the desert beetle in central Asia has...
