Protein methylation in pea chloroplasts.
The methylation of chloroplast proteins has been investigated by incubating intact pea (Pisum sativum) chloroplasts with [(3)H-methyl]-S-adenosylmethionine. Incubation in the light increases the amount of methylation in both the thylakoid and stromal fractions. Numerous thylakoid proteins serve as substrates for the methyltransfer reactions. Three of these thylakoid proteins are methylated to a...
متن کاملBritain Photosynthetic Control by Isolated Pea Chloroplasts
Isolated pea chloroplasts undergo both cyclic and non-cyclic electron flow. Both processes are coupled to photophosphorylation. During non-cyclic flow the rate of oxygen production showed ADP-governed 'photosynthetic control' analogous to respiratory control of isolated mitochondria. Measurements ofADP/O and photosynthetic control ratios yielded values of 1-1-3 and 2-5-7 respectively. 'Photosyn...
متن کاملFinal step of phosphatidic Acid synthesis in pea chloroplasts occurs in the inner envelope membrane.
The second enzyme of phosphatidic acid synthesis from glycerol-3-phosphate, 1-acylglycerophospate acyltransferase, was localized to the inner envelope membrane of pea chloroplasts. The activity of this enzyme was measured by both a coupled enzyme assay and a direct enzyme assay. Using the coupled enzyme assay, phosphatidic acid phosphatase was also localized to the inner envelope membrane, alth...
متن کاملInteraction of Herbicides with Pea Chloroplasts
Herbicides not only kill the weeds but also affect cell metabolism of economic crops, specifically their photosynthetic machinery [1]. They interfere with the development and structure of chloroplasts, thereby influencing light reactions of photosynthesis [2]. We report in this communication on the inter action of pyrazon, triazole and metribuzin with pea chloroplasts during greening in terms ...
متن کاملEndopeptidases in the stroma and thylakoids of pea chloroplasts.
Three endopeptidases (EP2, EP3, and EP4) were identified after fractionation of pea (Pisum sativum, var Feltham First) chloroplast stromal extracts. All three were identified by their ability to cleave in vitro-synthesized preplastocyanin to lower molecular weight forms. EP2 is inhibited by phenylmethylsulfonylfluoride, and both EP2 and EP3 are inhibited by the heavy metal chelators 1,10-phenan...
