Abstract
The in vitro synthesis of chitin via a nonbiosynthetic path has been achieved for the first time by enzymatic ring-opening polyaddition of a chitobiose oxazoline monomer (C2O). Chitinase, a hydrolysis enzyme of chitin, recognized and polymerized the monomer regio- and stereoselectively. The structure of artificial chitin was confirmed by comparison with an authentic natural chitin sample with the use of CP/MAS 13C NMR and IR spectroscopy. X-ray diffraction as well as NMR analysis showed its crystal structure of α-chitin. Characteristic features of the present polymerization are described.
