BBa_K398406 enables E.coli of working in two-phase systems with resistance to high concentrations of hydrophobic molecules in the membrane. A growth rate increase of 62% in comparison to a standard E.coli was achieved at concentrations of 8% (v/v) n-hexane.

Introduction

The effect of organic solvents to organisms can be detrimental: they can accumulate in the cell membrane changing the composition, thus affecting its physiological function. BBa_K398406 produces prefoldin, a protein from Pyrococcus horikoshii OT3. Prefoldin is a part of a widely spread group of proteins: chaperones. These proteins have the property of helping during the protein folding process, and are related also to thermal shock resistance. The prefoldin constists of two subunits: phPFDα and phPFDβ (Figure 1). These proteins increase the tolerance to alkanes by acting as chaperones, which correct protein misfolding /unfolding in the presence of alkanes.
