Table 1 Enzymes potentially involved in degradation of mucopolysaccharides (based on Wraith 2013) found in cephalopod egg capsules. Most of these enzymes do not have representative family in Carbohydrate Active EnZymes database (www.cazy.org). Cazy families of glycoside hydrolases that were identified either in bacterial or arthropodal scaffolds are showed below.
