Cover Story: Chitin deacetylases (CDAs) catalyze the hydrolysis of acetamido groups in GlcNAc residues of chitin, chitosan, and chitooligosaccharides (COS). The deacetylation specificity exhibited by CDAs is diverse, some enzymes being specific for single positions, others showing multiple attacks, processivity or random actions. The “subsite capping model” proposes that specificity is partly governed by a series of dynamic loops that shape the substrate binding cleft, which differ among CDAs on a highly conserved protein core. The structures, specificities, and biotech applications of bacterial and fungal CDAs are reviewed here. View the paper here.
