Cellobiohydrolase

Function Cellobiohydrolase (CBH) is a cellulase which degrades cellulose by hydrolysing the 1,4-β-D-glycosidic bonds. CBH is an exocellulase which cleaves two to four units from the ends of cellulose. There are two types of CBH. CBHI cleaves progressively from the reducing end while CBHII cleaves progressively from the nonreducing end of cellulose. Structural highlights The of CBH contains (Gln-Asp-Glu in 3cel, cyan) and is situated at the .
