Part:BBa_K3332020

phnE1

Subunit of phosphonate ABC transporter, permease protein phnE, from S.meliloti 1021.Use K823004 to construct a new part that can transport glyphosate to cytoplasm.

Biology

Phn system is a gene cluster for organophosphorus transport and degradation in many microorganisms. Sinorhizobium meliloti 1021 use PhnE1 and PhnE2 to construct the permease protein of ABC transporter, which includes PhnE1, PhnE2, PhnC and PhnD proteins, this transporter can transport glyphosate to cytoplasm. The phnE1 gene encodes a subunit of permease protein which can transport glyphosate to cytoplasm.

Usage

We ligased the strong promoter (BBa_J23100) and the parts (RBS-phnE1-Terminator) on the expression vector pSB1C3 by standard assembly. Then the ligation mixture was transformed into E. coli DH5α & E. coli BL21(DE3), enabled the E. coli to express PhnE1 protein.

Characterization

1. Agarose Gel Electrophoresis After receiving the synthesized DNA, restriction digestion was done to certify that the plasmid was correct, and the experimental results were shown in figure 1.
