l-Phenylalanine Ammonia-lyase (Maize) [PDF]
Plant Physiology, 1972 Extracts of maize leaf sheath tissue deaminate both l-phenylalanine and l-tyrosine. The activities with both substrates are enhanced by treating the plant with gibberellic acid. Both activities decrease rapidly at the same rate when tissue is incubated in a moist atmosphere, and this decrease can be slowed by treatment with cycloheximide.
