Fre-Linker-SttH

Construction of SttH and Fre fusion enzyme to enhance the solubility and activity of SttH.Fre is a unique N-terminal tag that efficiently enhanced SttH activity by increasing solubility as well as cofactor supply.

Biology

After linked the Fre to SttH, the total expression of SttH decreased, but all the chimeric enzymes showed highly increased ratios of their soluble forms in E. coli. The molar concentrations of soluble Fre-Linker–SttH was 1.64 μM, which was more than three times higher than that of SttH by itself[1].

Usage

We connected Fre and SttH through the Linker to enhance the solubility of SttH. Then the ligation mixture was transformed into E. coli DH5α, which enabled the E. coli to express SttH protein. Due to the limited time, we did not characterize this part. As a result, there is a lack of data about this part.
