The present invention refers to an enzyme consisting of a fusion protein particularly useful as shown through-out the present invention for carrying out the carbon-carbon bond-forming reaction known as the aldol Reaction, preferably for carrying out an aldol reaction by using aldehydes as substrates and preferably pyruvate or a salt thereof, for producing hydroxyketoacids. Said enzyme is made by binding an aldolase to a maltose binding protein. The enzymes display full activity under “highly denaturing” substrate loadings (aldehydes, >1 M).
本发明指的是一种由融合蛋白组成的酶,如本发明全文所示,这种酶特别适用于进行称为醛醇反应的碳-碳键形成反应,最好是通过使用醛作为底物,最好是
丙酮酸或其盐来进行醛醇反应,以生产羟基
酮酸。所述酶是通过将
醛缩酶与
麦芽糖结合蛋白结合制成的。这种酶在 "高度变性 "底物负荷(醛,>1 M)下显示出全部活性。
