ABSTRACT:
A novel tyrosine ammonia lyase enzyme was identified in the bacteriumRhodobacter sphaeroides. This enzyme has a higher activity for tyrosine than for phenylalanine and is useful for the production of para-hydroxycinnamic acid directly from tyrosine. The gene encoding this enzyme was cloned by direct amplification using the genomic DNA and was expressed inE. coli.
