The gene qutb was cloned to pbv220 , qdhase was expressed and had specific activity in e . coli . 3 . construction of co - expression recombinants of multigenes in a single plasmid pbv220 and its optimization according to different combined modes , six co - expression recombinants , each gene of which recombinant is under control of lambda phase prpl or pl promoter , were constructed and expressed 單質粒pbv220多基因串聯表達重組子的構建及優化以不同方式組合，構建了含有各自啟動子prpl或pl的二基因arog 、 qutb串聯表達重組子四種和三基因arog 、 qutb 、 arob串聯表達重組子二種。

The recombinants were constructed by transforming ppic9 a - xynb into p . pastoris gs115 . the assay results revealed that the xylanase gene xynb was overexpressed and secreted effectually in p . pastoris . in 3l fermentor the expression level of xylanase xynba exceeded 1200iu / ml and the expressed xylanase had normal bioactivity . the molecule weight of xynba was determined as about 31kd which is higher than 23kd of original enzyme xynb from streptomyces olivaceoviridis a1 . xynbb was gotten by deglycasylation of xynba , whose molecule weight returned to 23kd . we comparised the enzymatic properties of xynba expressed in p . pastoris , xynbb deglycasylated from xynba and xynb produced from streptomyces olivaceoviridis al : there was little difference among the three enzymes on optimal ph , the optimal ph of xynb and xynba were both 5 . 2 , the optimal ph of xynbb was 5 . 0 ; the optimal temperature of xynb and xynba were both 60 c , while the optimal temperature of xynbb was 50 ? ; because of glycosylation the thermal stability of xynba was better than xynb and xynbb ; the specific activity of xynba and xynbb were 883 . 88iu / mg and 832 . 5hu / mg respectively , which were both lower than 2814 . 45iu / mg of xynb ; the km values of xynb and xynba were similar to each other which were 21 . 56 ( g / kg ) and 20 . 87 ( g / kg ) , while the km value of xynbb was 27 . 10 ( g / kg ) ; the fmax of xynba and xynbb were 4568umol / mg . min and 5329umol / mg . min respectively which were lower than 27623 umol / mg . min of xynb ; additionally all of the three enzymes did not display cellulase activity . they all had well resistance to pepsion and trypsin , and were not sensitive to metal iron , surface active agent and chelating agent . the analysis of different xylans enzymatic hydrolysate revealed : by xynba , that the main constitutions of enzymatic hydrolysate of birch wood xylans were xylotriose and xyloquaiose , which account for 68 . 43 % and 16 . 50 % respectively , additionally there was 11 . 79 % of xylobiose ; the main constitutions of enzymatic hydrolysate of corncobs xylans were xylobiose and xylotriose , which account for 81 . 78 % and 11 . 55 % . the result indicated that this xylanase was a kind of 1 , 4 - b - d - xylanohydrolase and was fit to used in industrial procession of xylooligosacc harides 進一步對xynba進行了脫糖基化處理得到xynbb ,其分子量恢復到23kd ，證明xynba是糖基化蛋白。通過對畢赤酵母重組表達的木聚糖酶xynba 、脫糖基化的木聚糖酶xynbb以及橄欖綠鏈霉菌a1所產原酶xynb之間酶學性質的比較發現：三種酶的最適ph差異不大， xynb和xynba均為5 . 2 ， xynbb為5 . 0 ； xynb和xynba的最適溫度均為60 ， xynbb降為50 ：在耐熱性上， xynba由于糖基化作用熱穩定性明顯高于未糖基化的xynb和xynbb ； xynba和xynbb的比活性分別為883 . 88iu mg和832 . 51iu mg ，明顯低于原酶的比活2814 . 45iu mg ； xynb和xynba的km值相當，分別為21 . 56 ( g kg )和20 . 87 ( g kg ) ，而xynbb的km值較大為27 . 10 ( g kg ) ； xynba和xynbb的vmax相差不大，分別為4568 mol mg ? min和5329 mol mg ? min ，明顯低于xynb的27623 mol mg ? min此外三種酶均無纖維素酶活性，對胃蛋白酶和胰蛋白酶有很好的抗性，且對作用環境中的各種離子、表面活性劑、螯合劑不敏感。通過對不同木聚糖的酶解產物的糖份分析發現：以樺木木聚糖為底物時，酶解產物主要為木三糖和木四糖，含量分別為68 . 43和16 . 50 ，另外還含有11 . 79的木二糖；以玉米芯木聚糖為底物時，酶解產物主要為木二糖和木三糖，含量分別為81 . 78和11 . 55 。
