実験手順

The aspC and the proA genes were cloned into the pTrc99a expression vector (Amersham, Piscataway, N.J.). The resulting vector was transformed into the tryptophan auxotrophs CAG18455 or CAG18579 (see Example 4 for strain descriptions). The transformants were plated on M9 minimal medium with 0.1 mM IPTG and 5 mM monatin. After 3 days at 37° C., the strains with the operon plasmids formed colonies, while the parent strains did not appear to grow. Additionally, the growth was dependent on the presence of IPTG indicating that expression of the operon was required for growth. In this complementation study, the aspC/proA operon formed MP from monatin and indole-3-pyruvate from MP. The indole-3-pyruvate could then be converted to L-tryptophan allowing the tryptophan auxotrophs to grow on M9 minimal medium.
