3.5.1.41 acetylated chitosan oligosaccharide + H2O the recombinant isolated catalytic domain displays deacetylase activity on chitooligosaccharides with a degree of polymerization (DP) larger than 3, generating mono- and di-deacetylated products with a pattern different from those of closely related fungal CDAs. On a DP5 substrate, PcCDA gave a single mono-deacetylated product in the penultimate position from the non-reducing end (ADAAA) which is then transformed into a di-deacetylated product (ADDAA).

General Information

EC Number General Information Comment Organism
3.5.1.41 evolution chitin deacetylases belong to family 4 of carbohydrate esterases. All CE4 enzymes share the NodB homologous domain, with a distorted (beta/alpha)8 barrel structure17 that contains the catalytic active site Pochonia chlamydosporia
3.5.1.41 additional information the extracellular CE4 deacetylase has two CBM18 chitin binding modules, molecular modelling of the PcCDA catalytic domain and ligand docking using 2IW0 and 2Y8U as templates, overview. Structure-function relationships with regard to specificity and pattern of deacetylation. The catalytic domain (CE4 domain, residues 107 to 303) is flanked by two (N- and C-terminal) CBM18 modules (residues 30 to 74 and 360 to 441, respectively). These family 18 carbohydrate binding modules are typically involved in chitin binding. PcCDA full-length protein includes 25 cysteine residues, of which only two are located in the CE4 catalytic domain Pochonia chlamydosporia
3.5.1.41 physiological function the enzyme might have a role in pathogenicity Pochonia chlamydosporia
