'''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.<ref>PMID:9466911</ref>. The exo-acting CBH I is called '''Cel7A'''. The endo-acting CBH I is called '''Cel7B'''. | '''Cellobiohydrolase''' (CBH) is a cellulase which degrades [[cellulose]] by hydrolysing the 1,4-β-D-glycosidic bonds.
