Phenolic biosynthesis during grain development in wheat: changes in phenylalanine ammonia-lyase activity and soluble phenolic content
Changes in phenylalanine ammonia lyase (PAL) activity and the total phenolic content of several wheat cultivars have been monitored during grain development. PAL activity was maximal during the earlyExpand

A novel alliinase from onion roots. Biochemical characterization and cDNA cloning.
We have purified a novel alliinase (EC from roots of onion (Allium cepa L.). Two isoforms with alliinase activity (I and II) were separated by concanavalin A-Sepharose and had molecularExpand
