folKE + b0
Constitutive folKE expression construct
2008-07-27T11:00:00Z
2015-05-08T01:10:09Z
The original folKE gene was extracted from the L.lactis subspe. IL1403 genome.
Released HQ 2013
This is the folate synthesis gene folKE, one of five genes (folB, folKE, folP, folC, folA) involved in the folate synthesis operon. In this construct, folKE has been inserted behind the strong promoter j23100, the strong RBS b0034, and in front of the double terminator B0015. The vector is the inducible copy plasmid psB2K3, which can be induced to high copy via IPTG.
The purpose of this construct is to test the effects of folKE (a fusion gene for GTP cyclohydrolase I (folE) + 2-amino-4-hydroxy-6- hydroxymethyldihydropteridine pyrophosphokinase (folK)) overexpression on total folate production in Escherichia coli, with the goal of increasing total folate production.

FolKE has been shown to be a good target for metabolically engineering the overexpression of folate in bacteria, particularly in L.lactis. One possible explanation for this is that since GTP cyclohydrolase I is involved in the first enzymatic step in the folate biosynthesis pathway, overexpression of this enzyme will increase the total flux through the pathway.

L.lactis genome
folKE is a bifunctional gene which encodes two necessary enzymes for folate biosynthesis (2-Amino-4-hydroxy-6-hydroxymethyldihydropteridine pyrophosphokinase / GTP cyclohydrolase I).

It's complicated
false
We were unsure of whether or not the L.lactis RBS would work with E. coli and so we are going to try cloning the entire gene cluster with the RBSs as well as cloning out each gene separately and adding E.coli RBSs.

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <p>No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

<P> <P>Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG).<P> Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
