Transcellobiosylation Reactions Catalyzed by Different Exoglucanase Components of a Trichoderma viride Cellulase in Aqueous Organic Solvent

The last piece in the cellulase puzzle: the characterisation of β-glucosidase from the herbivorous gecarcinid land crab Gecarcoidea natalis

“…This suggests the ligation of two cellobiose units by transcellobiosylation rather than the progressive transglycosylation of cellobiose to cellotriose, and finally to cellotetraose. Transcellobiosylation reactions are a feature of fungal exocellulases (Hayashi et al, 2003;Okada and Nisizawa, 1975). A similar transient ligation step has been observed for -glucosidase from P. cribrata and the mealworm Tenebrio molitor (Ferreira et al, 2001;Scrivener and Slaytor, 1994).…”
