Hfq: Expression cassette under a xylose inducible promoter

Hfq is a protein which enhances sRNA complementation to its mRNA target - It does so by binding AU-rich and poly-A-rich sequences; Hfq-dependent sRNAs have greater target binding rate, target mRNA degradation, and half-life (Yoo et al., 2013). Species which are closely related to (and including) E. coli contain the Hfq gene in their chromosomes - other species, including Staphylococcus sp., will require this expression cassette if heightened sRNA activity is to be achieved. Illegal sites were removed and the sequence was codon optimized for expression in S. epidermidis using JCat software.

This part was DNA-Synthesized.
