Fig. 4From: Biochemical characterization of the xylan hydrolysis profile of the extracellular endo-xylanase from Geobacillus thermodenitrificans T12HPAEC elution pattern of with AaXynA and GtXynA1 incubated with beech wood xylan (BeWX) (a, b respectively) and wheat arabinoxylan (WAX) (c, d respectively) for 24 h, and respective cleavage pattern of GtXynA1 on BeWX (b*) and WAX (d*). • = xylosyl residue, ◊ = arabinosyl residue, ▲ = 4-O-methylglucuronic acid. (b) shows the identification of the main substituted xylo-oligosaccharide from B. The structure is identify based on its UV signal and the MS2 fragmentation patternBack to article page
