Preparation of an esterase
Abstract:
The present invention relates to a recombinant E. coli strain characterized in that the organisms contains a gene coding for a protein having esterase activity. Such E. coli is suitable for the preparation of a protein with esterase activity, whereby the expression takes place without coexpression of GroEL and/or GroES from a plasmid. The expression of glutathione reductase and/or thioredoxin reductase may be abolished by mutation. Furthermore, the ability of the organism to grow under oxygen-rich conditions has been restored by mutation. The expression of the gene of the protein with esterase activity is unaccompanied by the expression of an additional gene encoding a heat shock chaperone protein.
