== Function ==

[https://www.uniprot.org/uniprot/GUN1_HUMIN GUN1_HUMIN] The biological conversion of cellulose to glucose generally requires three types of hydrolytic enzymes: (1) Endoglucanases which cut internal beta-1,4-glucosidic bonds; (2) Exocellobiohydrolases that cut the dissaccharide cellobiose from the non-reducing end of the cellulose polymer chain; (3) Beta-1,4-glucosidases which hydrolyze the cellobiose and other short cello-oligosaccharides to glucose.

== Publication Abstract from PubMed ==

Cellulases and related beta-1,4-glucanases are essential components of lignocellulose-degrading enzyme mixtures. The detection of beta-1,4-glucanase activity typically relies on monitoring the breakdown of purified lignocellulose-derived substrates or synthetic chromogenic substrates, limiting the activities which can be detected and complicating the tracing of activity back to specific components within complex enzyme mixtures. As a tool for the rapid detection and identification of beta-1,4-glucanases, a series of glycosylated cyclophellitol inhibitors mimicking beta-1,4-glucan oligosaccharides have been synthesised. These compounds are highly efficient inhibitors of HiCel7B, a well-known GH7 endo-beta-1,4-glucanase. An elaborated activity-based probe facilitated the direct detection and identification of beta-1,4-glucanases within a complex fungal secretome without any detectable cross-reactivity with beta-d-glucosidases. These probes and inhibitors add valuable new capacity to the growing toolbox of cyclophellitol-derived probes for the activity-based profiling of biomass-degrading enzymes.
