Promoter of Heat Shock Proteins (HSPs) which consists of GroEL and GroES

Promoter of Heat Shock Proteins (HSPs) which consists of GroEL and GroES

Usage and Biology

The DNA sequence of Heat Shock Proteins (HSPs) in Synechococcus sp. PCC7942 had been figured out, which consists of GroEL and GroES.[1]It allows us to use the culture temperature to regulate the expression of downstream genes.

The promoter of HSPs is a strong promoter.About 2.3 kb transcript of groESL1 operon increased 30-fold within 30 min upon heat shock. It allows us to regulate the expression of target genes by changing the culture temperature, and avoid the risk of losing transformed algae strains for toxic effect caused by target genes.[1]

In our project，we have constructed the inducible expressing shuttle plasmid pgFQ and inserted bacterial cellulose into the homologous arm slr0168 (as shown in the figure below). We transformed the Synechocystis and measure the bacterial cellulose content of the transformants.
