Discs excised from Solanum tuberosum L. cv White Rose tubers demonstrated a 4.5-fold increase in chorismate mutase activity 48 hours after excision. Incubation in the presence of cycloheximide (25 micromolar) or actinomycin D (100 micromolar) completely inhibited the wound response suggesting de
An amino acid-sensitive form of chorismate mutase (CM) has been purified over 1000-fold from disks excised from tubers of Solanum tuberosum L. cv White Rose. Purification was accomplished by chromatography on Matrix Blue A followed by affinity chromatography with tryptophan as ligand. CM assays
