Fig. 8From: Inhibitory effect of lignin on the hydrolysis of xylan by thermophilic and thermolabile GH11 xylanasesSurface charge distribution on xylanases TrXyn1, TrXyn2 and Xyl40-CD calculated with Protein-Sol web tool. Charge at pH 6.3 a from the front of the active site palm region and b turned 180° from the back of the palm region. Cartoon image on Xyl40-CD to represent protein orientation. Negatively charged areas are shown in red and positively charged in blueBack to article page
