Chenopodium Rubrum

Cells from photoautotrophic cultures of Chenopodium rubrum were fractionated for the isolation of purified chloroplasts and mitochondria. The subcellular localization of the enzymatic activities involved in the metabolism of malic acid was investigated. Highly purified chloroplasts were obtained from the protoplasts, whereas peroxisomes were still present in the mitochondrial fraction. NAD - and NADP-dependent malate dehydrogenase and malic enzyme activities were found in the mitochondrial and chloroplast fractions, respectively. Exogenously supplied [14C]labelled malate was metabolized by the photoautotrophic cell suspension, obviously to the greater part in mitochondria.
