Abstract
The mRNA coding for phenylalanine ammonia‐lyase was partially purified from irradiated cell suspension cultures of parsley (Petroselinum hortense). The product of cell‐free translation of the mRNA in a reticulocyte lysate was isolated by immunoprecipitation and compared with the native enzyme subunit. Evidence for the identity, or at least a great similarity, of both was provided by tryptic‐peptide and gel‐electrophoretic analyses.Under partially denaturing conditions, phenylalanine ammonia‐lyase mRNA sedimented as a 20–21‐S molecule in a sucrose gradient and had an apparent molecular weight of about 1.05 × 106on a polyacrylamide gel. Approximately two‐thirds of the polynucleotide sequence of the mRNA were estimated to be required as coding sequence for the enzyme. We suggest that phenylalanine ammonia‐lyase mRNA is unlikely to code for more than one of three coordinately induced enzymes.
