Our new paper is out (free full-text until May 13th!): Chiam Yu Ng et. al., Rational Design of a Synthetic Entner-Doudoroff Pathway for Improved and Controllable NADPH Regeneration, Metabolic Engineering, 2015

Highlights: We re-engineered the Entner–Doudoroff pathway from Zymomonas mobilis to increase NADPH regeneration in E. coli by 25-fold. Operons expressing the 5-enzyme pathway were designed by our Operon Calculator algorithm and integrated into the E. coli genome. Pathway variants were characterized using enzyme assays, a NADPH-binding fluorescent reporter, and a NADPH-dependent biosynthesis pathway. Enzyme expression levels were efficiently optimized by combining our RBS Library Calculator algorithm with the Church Lab's MAGE genome mutagenesis technique.

RBS Calculator

Pre-Sequence [?]
Pre-Sequence: enter a nucleotide sequence (5 to 20 bp) that appears before the ribosome binding site, using A/G/C/T/U. The Pre-Sequence is important when the ribosome binding site is less than 35 nucleotides long. (optional)
Protein Coding Sequence [?]
Protein Coding Sequence: enter a nucleotide sequence (at least 50 bp) that encodes a protein, using A/G/C/T/U.
Begins with a start codon (ATG/GTG/TTG/CTG). (required)

Target Translation Initiation Rate [?]
Target Translation Initiation Rate: select the desired rate of translation initiation on a proportional scale from 0.1 to 100,000 or more. (required)

Proportional scale (0 to 100,000+) Goal: Maximize
Organism or (16S rRNA) [?]
Organism or 16S rRNA sequence: choose a bacterial species by typing in the first 3 letters of its name and selecting it from the list. Alternatively, you may enter the last 9 nucleotides of the 16S rRNA, using A/G/C/T/U.
(start typing)
