We propose that the first step in the generation of chitosan from chitin, deacetylation of chitin to obtain chitosan, is important. The deacetylase encoded by CDA can catalyze the deacetylation of chitin to synthesize chitosan. We cloned the CDA gene into the PET28a vector to obtain the PET-28a-CDA recombinant plasmid, which was transformed into E. coli BL21 (DE3) to overexpress CDA.

Design Notes

We aimed to investigate the relationship between the structure and function of chitosanase and to produce chitooligosaccharides with a defined degree of polymerization. To achieve this, amino acid mutation at site 115 was engineered to enhance enzymatic activity and to generate more uniform products.
