Reports from University of Munster highlight recent research in vector development

Published in Genetics and Environmental Business Week, July 24th, 2008

"Cyanophycin [multi-L-arginyl-poly(L-aspartic acid) (CGP)] was, for the first time, produced in yeast. As yeasts are very important production organisms in biotechnology, it was determined if CGP can be produced in two different strains of Saccharomyces cerevisiae," researchers in Munster, Germany report.

"The episomal vector systems pESC (with the galactose-inducible promoter GAL1) and pYEX-BX (with the copper ion-inducible promoter CUP1) were chosen to express the cyanophycin synthetase gene from the cyanobacterium Synechocystis sp. strain PCC 6308 (cphA(6308)) in yeast. Expression experiments with transgenic yeasts revealed that the use of the CUP1 promoter is much...
