This is an abbreviated version!
For detailed information about Pyrococcus furiosus beta-glycosidase, go to the full flat file.
Reaction
The enzyme produces mannose and glucose mainly from mannooligosaccharides and cellobiose by hydrolyzing them from the reducing end. It can not hydrolyze alpha-form substrates and bulk polymers like mannan and starch =

(5R,6R,7S,8S)-5-(hydroxymethyl)-2-phenyl-5,6,7,8-tetrahydroimidazol[1,2-a]pyridine-6,7,8-triol
1,3-dimethylimidazolium methylsulfate
the enzyme retains full catalytic efficiency for lactose hydrolysis at 80°C in a 50% (v/v) solution of the ionic liquid 1,3-dimethylimidazoliummethylsulfate in sodium citrate buffer, pH 5.5. It is inactive but not irreversibly denatured at 70% (v/v) ionic liquid
