Fig. 3From: CaXyn30B from the solventogenic bacterium Clostridium acetobutylicum is a glucuronic acid-dependent endoxylanaseTLC of model xylan and xylooligosaccharides digestions by CaXyn30B, the GA-dependent endoxylanase, BsXynC, and the previously described GA-independent endoxylanase, CaXyn30A. From left to right glucuronoxylan (sweetgum, SGX), arabinoxylan (wheat, WAX), aldotetrauronic acid (GX3), aldotriuronic acid (GX2), xylotetraose (X4), xylose to xylohexaose standards (X1-X6), aldouronate standards (GXn), xylopentaose (X5) and xylohexaose (X6)Back to article page
