An order‐of‐magnitude improvement in the production of phenylacetaldehyde to 3.37 M (405 g L−1) from the enzymatic isomerisation of styrene oxide was achieved. A small ubiquitin‐related modifier (SUMO) tag increases the productivity of the whole‐cell biocatalytic system by enhancing the expression of active membrane‐bound styrene oxide isomerase (SOI) while retaining enzyme catalytic efficiency and broad natural substrate scope. The isomerisation was performed by using Escherichia coli expressing SUMO‐tagged SOI in an organic‐aqueous biphasic system to yield 96% of phenylacetaldehyde.

使用融合标记的苯乙烯氧化物异构酶高产量生产苯乙醛

通过氧化苯乙烯的酶促异构化反应,苯乙醛的产量提高了一个数量级,达到3.37 M(405 g L -1)。一个小的泛素相关修饰剂(SUMO)标签通过增强活性膜结合的苯乙烯氧化物异构酶(SOI)的表达,同时保留酶催化效率和广泛的天然底物范围,从而提高了全细胞生物催化系统的生产率。通过使用在有机水双相系统表达SUMO标签的SOI的大肠杆菌进行异构化,可产生96%的苯乙醛。
