A modular enzyme with combined hemicellulose-removing and LPMO activity increases cellulose accessibility in softwood.

ABSTRACT: Because of the association with other complex polysaccharides, extracting and utilizing cellulose from lignocellulosic materials requires the combined action of a broad range of carbohydrate-active enzymes, including multiple glycoside hydrolases (GHs) and lytic polysaccharide monooxygenases (LPMOs). The interplay between these enzymes and the way in which Nature orchestrates their co-existence and combined action are topics of great scientific and industrial interest. To gain more insight into these issues, we have studied the lignocellulose-degrading abilities of an enzyme from Caldibacillus cellulovorans (CcLPMO10-Man5), comprising an LPMO domain, a GH5 mannanase domain and two family 3 carbohydrate-binding modules (CBM3). Using a natural softwood substrate, we show that this enzyme pro
