i.e. 2-(acetylamino)-4-O-[2-(acetylamino)-2-deoxy-beta-D-glucopyranosyl]-2-deoxy-D-glucopyranose. Besides being a nutrient, the heterodisaccharide product 4-O-(N-acetyl-beta-D-glucosaminyl)-D-glucosamine is a unique inducer of chitinase production in Vibrio bacteria that have the chitin oligosaccharide deacetylase producing ability. Chitin oligosaccharide deacetylase involved in the synthesis of this signal compound is one of the key enzymes in the chitin catabolic cascade of chitinolytic Vibrio strains

enzymatic production of defined chitosan oligomers with a specific pattern of acetylation using a combination of chitin oligosaccharide deacetylases, method evaluation and optimization, overview. Production of specific chitosan oligomers which are deacetylated at the first two units starting from the non-reducing end by the combined use of two different chitin deacetylases, namely NodB from Rhizobium sp. GRH2 that deacetylates the first unit and COD from Vibrio cholerae that deacetylates the second unit starting from the non-reducing end. Both chitin deacetylases accept the product of each other resulting in production of chitosan oligomers with a novel and defined PA. NodB deacetylates exclusively the GlcNAc unit at the non-reducing end. The chitin deacetylase activity of NodB is tested against GlcNAc1-6. NodB is not active towards GlcNAc1, but converts GlcNAc2-6 completely into mono-deacetylated chitosan oligomers
