F. Foor et al., PRODUCTION OF L-DIHYDROXYPHENYLALANINE IN ESCHERICHIA-COLI WITH THE TYROSINE PHENOL-LYASE GENE CLONED FROM ERWINIA-HERBICOLA, Applied and environmental microbiology, 59(9), 1993, pp. 3070-3075
The gene (tutA) encoding tyrosine phenol-lyase from Erwinia herbicola
was cloned into Escherichia coli, and fusions to the lac and tac promo
ters were constructed. The enzyme was expressed at high levels in E. c
oli in the presence of isopropyl-beta-D-thiogalactopyranoside or lacto
se as an inducer. L-Dihydroxyphenylalanine was synthesized in high yie
ld from catechol, pyruvate, and ammonia by induced cells.
