'''SOLUTION STRUCTURE OF TACHYCITIN, AN ANTIMICROBIAL PROTEIN WITH CHITIN-BINDING FUNCTION'''
===SOLUTION STRUCTURE OF TACHYCITIN, AN ANTIMICROBIAL PROTEIN WITH CHITIN-BINDING FUNCTION===




==Overview==
<!--
Tachycitin, a 73-residue polypeptide having antimicrobial activity is present in the hemocyte of horseshoe crab (Tachypleus tridentatus). The first three-dimensional structure of invertebrate chitin-binding protein was determined for tachycitin using two-dimensional nuclear magnetic resonance spectroscopy. The measurements indicate that the structure of tachycitin is largely divided into N- and C-terminal domains; the former comprises a three-stranded beta-sheet and the latter a two-stranded beta-sheet following a short helical turn. The latter structural motif shares a significant tertiary structural similarity with the chitin-binding domain of plant chitin-binding protein. This result is thought to provide faithful experimental evidence to the recent hypothesis that chitin-binding proteins of invertebrates and plants are correlated by a convergent evolution process.
