l-Phenylalanine ammonia-lyase has been purified from elicitor-treated alfalfa (Medicago sativa L.) cell suspension cultures using two protocols based on different sequences of chromatofocusing and hydrophobic interaction chromatography. Three distinct forms of the intact enzyme were separated on the basis of affinity for Octyl-Sepharose, with isoelectric points in the range pH 5.1 to 5.4. The native enzyme was a tetramer of M(r) 311,000; the intact subunit M(r) was about 79,000, although… CONTINUE READING
