RBS-gapA-RBS-mdh-TT
It encodes glyceraldehyde-3-phosphate dehydrogenase and NAD dependent malate dehydrogenase.
Usage and biology
gapA could transform 3- phosphoglyceraldehyde into 1,3- diphosphoglycerate and mdh could transform malate into pyruvate. With the overexpression of gapA-mdh, Shewanella could produce NADH more efficiently, which brings more electricity being produced.
Characterization
This is one section contained two genes for NADH production part.
DNA Gel Electrophoretic
To make sure that we get the target gene, we did the DNA gel electrophoretic to separate different gene. And here is the result.
Our target genes are 2666bp, and as the marker is DS5000, we could be sure that the bright bands in this picture are our target genes.
Real-Time Quantitative PCR
To demonstrate that gapA could be overexpressed by engineered Shewanella, we did Real-Time Quantitative PCR.
There was no signal in bacteria which contained pYYDT so we chose pYYDT-gapA as standard quantity.
Electrogenesis
By comparing the ability of producing electricity, we might find out whether lldEFG could effectively help Shewanella to produce more electricity.
It could be demonstrated that targeted gene could be expressed in the engineered cells. More NADH has been produced by engineered bacteria, which helps to produce more electricty.
