Activity of phosphatidylcholine-transfer protein from spinach (Spinacia oleracea) leaves with mitochondria and chloroplasts.
A low-molecular-weight protein catalysing the transfer of phosphatidylcholine from liposomes to mitochondria and chloroplasts has been isolated from spinach (Spinacia oleracea) by chromatography on Sephadex G-75.
متن کاملDe Novo Maltotriose Biosynthesis from the Reducing End by Spinacia oleracea L. Chloroplasts.
The distribution of (14)C in the various glucose residues of maltotriose was studied as a function of time of photosynthesis of isolated chloroplasts of spinach (Spinacia oleracea L.) using (14)CO(2). The distribution of label showed that the reducing-end glucose residue was labeled first and the label subsequently distributed to the second and third glucose residues at approximately equal rate...
متن کاملLinoleate and alpha-linolenate synthesis by isolated spinach (Spinacia oleracea) chloroplasts.
Diacylgalactosylglycerol synthesis was a prerequisite for the incorporation of [1-14C]-acetate into linoleate and alpha-linolenate of isolated spinach (Spinacia oleracea) chloroplasts. Oleate at position 1 of diacylgalactosylglycerol was desaturated to linoleate and alpha-linolenate both in the light and in the dark. Some desaturation of palmitate was also observed after prolonged incubations.
متن کاملOn the control of long-chain-fatty acid synthesis in isolated intact spinach (Spinacia oleracea) chloroplasts.
1. Chloroplasts isolated from spinach leaves by using the low-ionic-strength buffers of Nakatani & Barber [(1977) Biochim. Biophys. Acta.461, 510-512] had higher rates of HCO(3) (-)-dependent oxygen evolution (up to 369mumol/h per mg of chlorophyll) and higher rates of [1-(14)C]acetate incorporation into long-chain fatty acids (up to 1500nmol/h per mg of chlorophyll) than chloroplasts isolated ...
متن کاملCircular Dna Molecules Associated with Chloroplasts of Spinach, Spinacia Oleracea
Results of cytochemical studies (Sagan and Scher, 1961 ; Ris and Plaut, 1962 ; Kislev et al ., 1965) and of studies involving cell fractionation and buoyant density analyses (Sager and Ishida, 1963 ; Ray and Hanawalt, 1964 ; Brawerman and Eisenstadt, 1964 ; Edelman et al ., 1964 ; Wells and Birnstiel, 1969) have shown that chloroplasts of microorganisms and of higher plants contain DNA which is...
