The light induced synthesis of phenylalanine ammonia-lyase in disks cut from potato tubers is very sensitive to cycloheximide. Synthesis is inhibited 50% in disks cultured on 5 mum cycloheximide instead of water and almost completely in disks aged in the presence of 10 mum inhibitor. Inhibition is irreversible. Fresh disks exposed only 1 hour to 10 mum cycloheximide do not synthesize enzyme during the subsequent 24 hours.Normally a maximal enzyme activity develops in disks about 24 hours after… CONTINUE READING
