MaSp1 : a spider silk protein used as a bioglue, optimised for Saccharomyces cerevisiae
Description
MaSp1 is a spider silk protein that can be used as a bioglue. The dragline protein MaSp1 containing numerous alanine and glycine residues tends to form considerable β-sheet and random coil secondary structure, which account for the crystalline fraction of cobwebs and confer inherently remarkable mechanical properties. The adhesion strenght of MaSp1 : 22.7 mJ/m².
Construction
The MaSp1 gene was synthesised and its nucleotide sequence optimised for synthesis and expression in Saccharomyces cerevisiae. This protein is used in fusion with a barnacle ciment protein as a bioglue, to improve its adhesive properties: BBa_K5143003
