ChiA comprises an N-terminal domain, a catalytic (beta/alpha)8 barrel domain and a small (alpha +beta) domain, which is inserted into the (beta/alpha)8 barrel domain. The cocrystallized chito-oligosaccharide is inserted into the catalytic cleft from the reducing end when digested by ChiB | Serratia marcescens |

General Information | Comment | Organism |
---|---|---|
physiological function | digestion of beta-chitin by ChiA occurs from the reducing end to the nonreducing end. Chitinases ChiA and ChiB show synergistic interactions in simultaneous degradation of beta-chitin, but not of glycol chitin | Serratia marcescens |
