J23102-RBS003422-gshF-T0

Description

The composite part is a generator consisting of J23102 promoter and gshF coding.

Usage

The J23102(BBa_J23102) promoter and gshF(BBa_K4325003) were connected and inserted into the pSEVA331 expression vector so that gshF expressed the neotype bifunctional enzyme GshF, which directly catalyze the synthesis of glutathione by the three kinds of amino acids, Cys, Glu and Gly.

1.Characterization in E. coli TOP10

As shown in Figure 2, composite part J23102-RBS0034-gshF-T0 and the expression of GshF were verified successfully by PCR amplification and SDS-PAGE respectively. As well as GSH production was detected.

2.Characterization in G. hansenii ATCC53582

Figure3 (a) showed that the size of the DNA fragments amplified from G. hansenii , thus confirming the successful incorporation of the plasmid and Figure2 (b) showed that the GSH production in G. hansenii.
