A previous study in this laboratory (12) indicated that leaves and excised roots of bush beans grown under conditions of Fe deficiency fixed larger quantities of C1402 from an enriched atmosphere than did those receiving adequate amounts of Fe. For this reason, studies have been made to determine the effect of Fe and chelating agents on PEP (phosphoenolpyruvate) carboxylase (1, 9, 13), PEP carboxykinase (9), and the carboxylation enzyme (17) systems that fix CO2.
