摘要:
Diclosed is a cloned gene encoding tryptophan synthase A and/or B. A recombinant plasmid containing the tryptophan synthase gene, an E. coli transformant transformed with the recombinant plasmid and a process of producing tryptophan synthase by culturing the transformant are also disclosed.
摘要:
A cloned tyrosine phenol-lyase gene encodes an amino acid sequence represented by the formula [I] below, which can be expressed in the absence of tyrosine in culturing medium. A recombinant vector containing the tyrosine phenol-lyase gene as well as E. coli transformants capable of producing tyrosine phenol-lyase are disclosed. Formula [I]:
