EstA : inactive fusion protein for bacterial surface expression

EstA is a membrane bound but inactive esterase from Pseudomonas aeruginosa. It can be used (unlike https://parts.igem.org/Part:BBa_K633001 BBa_K633001) for the cell surface expression of enzymes. Similiar to OmpA it allows to perform bacterial display of e.g. hydrolases like it has already been shown by Becker, Theile, Heppeler & Michalczyk, 2005. We used EstA to create our chimeric protein BBa_K808030 (Figure 1).

Cold adapted Esterase

A cold-adapted esterase was extracted from psychrotrophic bacterium Pseudoalteromonas sp. strain 643A, which is present in the alimentary tract of Antarctic krill Euphasia superba Dana. This protein consists of 206 amino acids residue with a molecular mass of 23,036 Da and belongs to the member of the GDSL-lipolytic enzymes family.1
