RBS-lldP-RBS-ldhA-TT
L-lactate permease & D-lactate dehydrogenase
Usage and biology
It encodes L-lactate permease and D-lactate dehydrogenase, which could produce and transport lactate. lldP could transport lactate out of the cell. ldhA could convert pyruvate to D-lactate. In this way, Rhodopseudomonas palustris could efficiently transport produced lactate out of the cell, which later will be used by Shewanella.
Characterization
This is one section for lactate production and transportation part.
DNA Gel Electrophoretic
To make sure that we get the target genes, we did DNA gel electrophoretic for verification. And here is the result.
Our target genes are 2739bp, and as the marker is DS5000, we could be sure that the bright bands in this picture are our target genes.
Electrogenesis
By detecting the production of lactate after expressing, we might find out whether RBS-lldP-RBS-ldhA-TT could effectively help Rhodopseudomonas palustris transport produced lactate out of the cell.
It could be demonstrated that the target genes could be expressed in the engineered cells. More lactate has been produced and transported by engineered bacteria.
