3.2.1.200 additional information processive enzyme, in which the substrate remains bound to the active cleft after successful hydrolysis and is moved along for the next hydrolysis to occur. ChiB performs on average 3.4 cleavages, for the formation of each enzyme-substrate complex. The exo-type of activity observed for ChiB during the degradation of solid crystalline chitin is due to the better accessibility of chain ends. When hydrolyzing soluble substrates, ChiB operates in a processive endo-attack mode of action Serratia marcescens ?
