Chitinase and chitosanase
WebThe glycohydrolase superfamily can be structurally divided into a bacterial family (chitosanase and T4L), and a eucaryotic family represented by chitinase, GEWL, and HEWL. Both families contain the ancestral core but differ at the amino and carboxy termini. The eucaryotes have a small N terminal domain, while the procaryotes have none.
