  • Patent number: 7195904
    Abstract: The present invention relates to an improved process for producing hydroxynitrile lyases. A process is provided whereby hydroxynitrile lyases may be produced by cultivation in bacteria or suitable host cells. Cells containing a gene encoding for a hydroxynitrile lyase may be precultivated, induced with a low concentration of IPTG, cultured, and lysed. The process allows for the production of relatively large quantities of hydroxynitrile lyases in a dissolved, native, and active form, and without the presence of substantial amounts of inclusion bodies, and thus allowing for the production of the lyases without requiring expensive and time consuming renaturation steps.
