abstract：:In a previous study (Melzer and O'Leary, 1987, Plant Physiol. 84, 58-60), we used isotopic methods to show that a substantial fraction of protein-bound aspartic acid in tobacco is derived from anaplerotic synthesis via phosphoenolpyruvate (PEP) carboxylase. Similar studies in soybean (Glycine max L.) and spinach (Spin...
