The naphthoquinone pigment shikonin from Lithospermum erythrorhizon Sieb. et Zucc. (Boraginaceae) was the first plant secondary metabolite produced in industrial scale from plant cell cultures. We have now manipulated the biosynthetic pathway leading to shikonin in L. erythrorhizon by introduction of the bacterial gene ubiA. This gene of Escherichia coli(More)
We analyzed the involvement of chaperonins GroES and GroEL in the biosynthesis of the three hydrogenase isoenzymes, HYD1, HYD2, and HYD3, of Escherichia coli. These hydrogenases are NiFe-containing, membrane-bound enzymes composed of small and large subunits, each of which is proteolytically processed during biosynthesis. Total hydrogenase activity was(More)
Creating and modifying Macro-Files can be a laborious task when using the wrong editor. However, Macro-Files are the only possibility to build macros and to define their appearance in the DELT/A. On this account, the Macro Editor was developed. Its graphical user interface is divided into different views each corresponding to a specific part of the file.(More)
