TDH3 promoter

a Constitutive improved promoter from Saccharomyces cerevisiae

Glyceraldehyde-3-phosphate dehydrogenase, -3- three glyceraldehyde dehydrogenase promoter (tdh1, tdh2, tdh3, tdh1) for weak promoter, tdh3 promoter, 3 phosphoglyceraldehyde catalytic oxidation (dehydrogenation) and phosphorylation of 1,3- - generation, is the central link of glucose metabolism, plays an important role in sugar metabolism.

TDH3.jpg

TDH3 from kit plate,the construct was transfected into Saccharomyces cerevisiae cells, the green fluorescence was observed under fluorescence microscope clearly. It indicates this part could work.

Yeast tutu.png

Truncated TDH3 promoter,the construct was transfected into Saccharomyces cerevisiae cells, the green fluorescence was observed under fluorescence microscope clearly.


Improved design:

We construct the device： TDH3 promoter+GFP+ADH1 terminator. TDH3 promoter is a truncated promoter, GFP is a mutant. These is a invariable sequence upstream of GFP coding sequence.

Characterization：
