xyn, Endo-xylanase
Xyn isAn endoxylanase gene without the signal peptidesequence. The enzyme was categorized as a glycosyl hydrolase family 11 member based on the sequence analysis of the putative catalytic domain. The main product of hydrolysis by Xyn is xylooligosaccharide.

We try to detect the activity of enzymes with 3,5-Dinitrosalicylic acid, but it is not so obvious. We speculate this might result from the facts that there is a big difference of the expression of foreign protein among different carriers of Pichia pastoris or different yeast strain, and that inappropriate ferment condition can result in low or even no activity of enzymes. In future research, we will try to enhance activity of enzymes by picking up suitable carriers and yeast strains and figuring out the optimal reaction conditions.
