Antigens closely resembling or identical to the three glycolytic enzyme
proteins phosphate-glycerate kinase, glyceraldehyde-3-phosphate
dehydrogenase, and aldolase are found in situ in the nucleus of the leaf
mesophyll cells of pea (Pisum sativum L.). These proteins have already been
identified in vertebrate nuclei. Apparently, these enzymes are nuclear
proteins with "secondary" roles not directly related to their enzymatic
function in carbon metabolism in both animals and plants.
