Enhanced hydrolytic efficiency of an engineered CBM11-glucanase enzyme chimera against barley β-d-glucan extracts

•- End-to-end fusion of a 1,3–1,4-glucanse with a family 11 carbohydrate-binding module.•- The heterologous chimera has catalytic activity and native-like secondary structure.•- The chimera shows increased catalytic efficiency as compared to the unfused enzyme.•- The chimera shows increased hydrolysis of malted and unmalted crude barley extracts.
