abstract：:The fate of the carbon-20 atom in gibberellin (GA) biosynthesis was studied in a cell-free system from Pisum sativum. This carbon atom is lost at the aldehyde stage of oxidation when C20-GAs are converted to C19-GAs. Gibberellin A12 labeled with (14)C at C-20 was prepared from [3'-(14)C]mevalonic acid with a cell-free...
