Abstract
A novel E. coli (KCCM 10,013) which can produce high yields of L-phenylalanine and a method for production of L-phenylalanine by recombinant E. coli which may be transformed with a novel plasmid pMW16 containing two promoters and a temperature-sensitive repressor for expressing a pheA gene and an aroF gene wherein chorismate mutase p-prephenate dehydratase is coded for by the pheA gene and 3-deoxy-D-arabinoheptulosonate.7-phosphate synthase is coded for by the aroF gene.
