The activities of NADP-dependent malate dehydrogenases in greening etiolated maize leaves were studied. "Malic" enzyme (EC 1.1.1.40) in bundle sheath cells developed slower as compared to NADP-malate dehydrogenase synthesizing malic acid in mesophyll chloroplasts. The increase in "malic" enzyme activity in the light was suppressed by protein synthesis inhibitors--chloramphenicol and cycloheximide. Possible localization of enzyme protein synthesis is discussed.
