Kazal type inhibitor from salivary glands of Aedes aegypti mosquito
Structural highlights
FunctionPublication Abstract from PubMedBlood-feeding exoparasites are rich sources of protease inhibitors, and the mosquito Aedes aegypti, which is a vector of Dengue virus, Yellow fever virus, Chikungunya virus and Zika virus, is no exception. AaTI is a single-domain, noncanonical Kazal-type serine proteinase inhibitor from A. aegypti that recognizes both digestive trypsin-like serine proteinases and the central protease in blood clotting, thrombin, albeit with an affinity that is three orders of magnitude lower. Here, the 1.4 A resolution crystal structure of AaTI is reported from extremely tightly packed crystals ( approximately 22% solvent content), revealing the structural determinants for the observed inhibitory profile of this molecule.
