Abstract: Isolation of the tyrB gene present in E. coli ATCC 11303 and cloning thereof in a multicopy plasmid results, after the transformation of the initial strain with this plasmid, in a 10-fold increase in the yield of L-phenylalanine.

Abstract: A replicating extra-chromosomal element contg. the isolated tyrB gene from E.coli ATCC 11303 is new. Also new are (1) E.coli ATCC 11303 (or its variants or mutants) transformed with these elements and (2) the tyrB gene. Pref. the element is a multicopy plasmid, specifically pAT153.

Abstract: The ilvE gene from the strain E. coli ATCC 11303 is suitable for achieving overproduction of the coded aliphatic transaminase and thus for preparing the branched-chain amino acids leucine, isoleucine and valine from the corresponding keto precursors.
