Cloned tyrosine phenol-lyase gene, recombinant plasmid containing it and E. coli transformed with the plasmid.

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]: <IMAGE> <IMAGE>
