Function

EBDG_AMYOR Hydrolyzes chitosan and chitooligosaccharides with retention of anomeric configuration. Has maximum activity on chitotetraose, chitopentaose and their corresponding alcohols, with a slight decrease in the rate of hydrolysis on longer chains. Has no activity against beta-D-glucopyranoside, beta-D-xylopyranoside, beta-D-mannoside, beta-D-glucuronide, beta-D-galactoside, beta-D-N-acetylgalactosamide, beta-D-N-acetylglucosaminide and alpha-D-N-acetylglucosaminide.^{[1] [2]}
