Cp19k : a barnacle cement protein used as a bioglue, optimised for Saccharomyces cerevisiae

Description

Barnacle, a marine organism, easily stick to underwater matrices through the secretion of various proteins and forming cement complexes. The protein complex for barnacle, Cp19k plays a key role in interfacial adhesion. Adhesion strength: 2.2 mJ/m². See BBa_K3089008 which provided the inspiration for the discovery of this sticky protein.

Construction

The Cp19k gene was synthesised and its nucleotide sequence optimised for synthesis and expression in Saccharomyces cerevisiae. This protein is used in fusion with spider silk protein as a bioglue, to improve its adhesive properties: BBa_K5143003
