Title
Messenger RNA-controlled Increase of Phenylalanine Ammonia-Lyase Activity in Parsley
Joachim Schröder; Brigitte Betz; Klaus Hahlbrock PLANT PHYSIOLOGY 1977. doi:10.1104/pp.60.3.440
Other claims from this paper (6)
- Observation Dilution and irradiation induced immunologically identical phenylalanine ammonia-lyase species in parsley cultures.
- Observation Dilution briefly increased the rate of parsley enzyme synthesis.
- Observation The enzyme synthesis rate peaked after 5 to 6 hours and then rapidly declined.
- Association In vivo and in vitro enzyme synthesis trajectories coincided with the active enzyme appearance trajectory.
- Intervention effect Dilution did not significantly change overall radioactive incorporation into protein in vivo.
- Intervention effect Dilution did not significantly change general polyribosomal RNA template activity in vitro for at least 25 hours.
