Activities of phenylalanine ammonia-lyase (PAL) and tyrosine ammonia-lyase (TAL) were assessed at each stage of a three-step purification of PAL. Assays were performed by high-performance liquid chromatographic (HPLC) separation and ultraviolet detection of reaction products. Use of HPLC permitted
l-Phenylalanine ammonia-lyase (PAL) activity develops in excised bean axes after approximately 5 hours of incubation and reaches a maximum level after 14 hours of incubation. Light does not affect the development of activity, but puromycin, cycloheximide, actinomycin D, and 5-fluorouracil
Limited literature is available concerning the phenolic biosynthesis and antioxidative potential of common bean sprouts induced by ultrasound elicitation. In this study, common bean seeds were treated with ultrasound at different power (0, 180 and 360 W) and time (0, 30, 45 and 60 min) levels,
