'''SOLUTION STRUCTURE OF DROSOMYCIN, THE FIRST INDUCIBLE ANTIFUNGAL PROTEIN FROM INSECTS, NMR, 15 STRUCTURES'''
===SOLUTION STRUCTURE OF DROSOMYCIN, THE FIRST INDUCIBLE ANTIFUNGAL PROTEIN FROM INSECTS, NMR, 15 STRUCTURES===




==Overview==
<!--
Drosomycin is the first antifungal protein characterized recently among the broad family of inducible peptides and proteins produced by insects to respond to bacterial or septic injuries. It is a small protein of 44 amino acid residues extracted from Drosophila melanogaster that exhibits a potent activity against filamentous fungi. Its three-dimensional structure in aqueous solution was determined using 1H 2D NMR. This structure, involving an alpha-helix and a twisted three-stranded beta-sheet, is stabilized by three disulfide bridges. The corresponding Cysteine Stabilized alpha beta (CS alpha beta) motif, which was found in other defense proteins such as the antibacterial insect defensin A, short- and long-chain scorpion toxins, as well as in plant thionins and potent antifungal plant defensins, appears as remarkably persistent along evolution.
