Abstract
Two recombinant plasmid Escherichia coli strains containing amplified fumarate reductase activity converted fumarate to succinate at significantly higher rates and yields than a wild-type E. coli strain. Glucose was required for the conversion of fumarate to succinate, and in the absence of glucose or in cultures with a low cell density, malate accumulated. Two-dimensional gel electrophoretic analysis of proteins from the recombinant DNA and wild-type strains showed that increased quantities of both large and small fumarate reductase subunits were expressed in the recombinant DNA strains.
