Besides, vgb gene expression also increased the chitinase secretion. in order to make the vitreoscilla hemoglobin gene express in bacillus subtilis, an inducible promoter ( levansucrase ) was cloned from b. subtilis wb600 and ligated with a promoter - less vgb gene. the resulted gene is called sacvgb and was demonstrated to express in e, coli by sds - page and carbon monoxide binding assay
由於vgb基因啟動子不能在枯草桿菌中啟動表達,因此,根據已發表的果聚糖蔗糖酶基因( sacb )序列設計引物,從枯草桿菌wb600總dna中擴增出該基因的啟動子片段,然後將其與vgb基因編碼區及終止子序列相連,成功地組建了sacvgb融合基因。Fos contain mixture of gf2, gf3 and gf4 sugars ( where g = glucose molecule and f = fructose molecule ) and a dp ( “ degree of polymerization ” ) of 3 - 5 ( “ neosugar ” ), are not naturally - occurring but are enzymatically synthetized from sucrose by action of an enzyme from the fungus aspergillus niger
詳細說明:是以蔗糖做底物,採用呋喃果糖苷酶轉果糖基作用,在蔗糖分子上以( 1 2 )糖苷鍵上與1 - 3個果糖分子結合,形成的蔗果三糖( gf2 ) 、蔗果四糖( gf3 ) 、蔗果五糖( gf4 )屬于果糖和蔗糖構成的直鏈雜低聚糖,在形成的產物中還有果糖、葡萄糖和未反應完全的底物蔗糖,採用色譜法除去單糖和雙糖制得高純度的低聚果糖。
