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 | Comment | Organism |
---|---|---|
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 |
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 |
physiological function | the enzyme might have a role in pathogenicity | Pochonia chlamydosporia |
