Klac gene was ligated to the pet - 30a ( + ) vector for expression . then the recombinant plasmid petlac4 was transformed into e . coli bl21 . the positive transformants were induced at different temperature for three hours by iptg with the final concentration of lmm . sds - page analysis and lactase activity assay showed that klac gene was expressed in e . coli , and that the expression level at 28 was much higher than that at 37 表達產物的sds - page分析和酶活性測定表明， klac基因在大腸桿菌中獲得活性表達，其中低溫條件28下的表達水平明顯高于37 ， 28誘導的細胞經超聲波破碎所測酶活力為0 . 475u / ml ， 37僅為0 . 134u / ml 。
So the lactase was suitable to whey at ph7 . 0 , but could n ' t react at high tempreture . the metals , fe2 + , mn2 * , ca2 + , mg2 + and zn2 + , can prominently improve lactase activity , but cu2 + would strongly inhibit the activity . according to the effect of edta , we concluded that the lactase depends on metal ions in a certain extent 乳糖酶基因klac在巴斯德畢赤酵母中表達將klac基因插入到載體ppic9上構建重組表達質粒pic9154983 ，電擊轉化巴斯德畢赤酵母受體菌gs115 ，經篩選和pcr鑒定， 1 # 、 8 #和24 #為重組菌株， klac基因整合到gs115基因組中。
Klac gene was inserted into the vector ppic9 to construct recombinant plasmid p1c9154983 , and then pic9154983 was transformed by electricity pulse into gs115 , pichia pastoris acceptor . after screening , we obtained recombinant yeast 1 # , 8 # and 24 # , that is , klac gene was integrated into the genome dna of gs115 . by detecting the lactase activity , we knew that the klac gene was expressed in vivo of pichia pastoris , but the lactase was not secreted 三個重組菌株經甲醇誘導培養未檢測到分泌的乳糖酶，但胞內均檢測到有活性的乳糖酶，分別為0 . 1392u / ml 、 0 . 3702u / ml和0 . 2214u / ml ，說明乳糖酶基因klac在巴斯德畢赤酵母中獲得表達。
The lactase gene from kluyveromyces lactis was researched in the thesis . the cloned gene was expressed in e . coli and the properties of lactase was determinated . in addition , we studied the expression of lactase gene in the methylotrophic yeast pichia pastoris 本論文從一株乳酸克魯維斯酵母菌中克隆獲得乳糖酶基因，在大腸桿菌中進行表達并測定其酶學性質，同時也對利用巴斯德畢赤酵母( pichiapastoris )系統表達該基因進行了探索。
Preparing the lactase solution expressed in e . coli , we determinated the optimum ph , ph stability , optimum reaction tempreture , thermal stability , effect of metal ions and chemical reagent , km and vmax its optimum ph was 5 . 8 and 6 . 4 to 7 . 5 , and the optimum tempreture was 45 to 52 以onpg為底物，分別測定了其最適ph值及ph穩定性、最適溫度及熱穩定性、金屬離子和化學試劑的影響以及k _ m值和v _ ( max )值。
Cloning and expression in e . coli of lactase . specific primers were designed according to the sequence of the beta - galactosidase gene from kluyveromyces lactis . klac gene was amplified by pcr and subsequently cloned 乳糖酶基因的克隆及原核表達以乳酸克魯維斯酵母( kluyveromyceslactis )菌株k538的基因組dna為模板，設計引物，利用pcr獲得乳糖酶基因klac ，經dna測序驗證，得到克隆t1549 。
This disorder , apparent within 10 days of birth , occurs when brush - border lactase activity ( required for the digestion of lactose ) in the small intestine is low or absent at birth and is characterized by diarrhea and malabsorption 此病是由于寶寶出生時小腸內的乳糖分解酶素活性很低或沒有活性，病癥通常在寶寶出生10天內顯現：拉肚子以及吸收不良。
