General Information

EC Number General Information Comment Organism
3.2.1.4 evolution species of Zygentoma that displayed the highest relative cellulase activity levels when compared to all other tested insect groups under the experimental conditions, including model species for cellulolytic systems such as termite and cockroach species in Rhinotermitidae (formerly Isoptera) and Cryptocercidae (formerly Blattodea). Among Zygentoma, Thermobia domestica was found to have higher endoglucanase, xylanase and pectinase activities compared to Ctenolepisma longicaudata. Among the identified enzymes are putative endoglucanases matching to insect or arthropod enzymes and glucan endo-1,6-beta-glucosidases matching bacterial enzymes. These findings support combined activities of endogenous and symbiont-derived plant cell wall degrading enzymes in lignocellulose digestion in Zygentoma, a primitive insect group Thermobia domestica
