title: [Glycolytic activity of enzyme preparation from the red king crab (Paralithodes camtschaticus) hepatopancreas].
abstract: Enzyme preparation exhibiting glycolytic activity yielding chitooligosaccharides along with N-acetyl-D-glucosamine was obtained from the red king crab (Paralithodes camtschaticus) hepatopancreas. The results of the analysis confirmed the presence of endo- and exochitinase activities in the preparation. HPLC showed that the hydrolysis products of chitin and chitosan did not contain D(+)-glucosamine, which is indicative of the absence of deacetylase and, apparently, exochitosanase activities. A comparison of the dependence of the enzyme preparation activity on temperature and pH of the incubation medium suggests that chitinase and protease activities are exhibited by different enzymes.
