Studies on the assembly of large subunits of ribulose bisphosphate carboxylase in isolated pea chloroplasts
Ribulose bisphosphate carboxylase consists of cytoplasmically synthesized "small" subunits and chloroplast-synthesized "large" subunits. Large subunits of ribulose bisphosphate carboxylase synthesized in vivo or in organello can be recovered from intact chloroplasts in the form of two different complexes with sedimentation coefficients of 7S and 29S. About one-third to one-half of the large sub...
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 کاملKinetic studies on the mechanism of the malate dehydrogenase reaction.
This work is a kinetic investigation of the reaction mechanism of malate dehydrogenase, prepared from washed mince of whole bovine heart by a variation on previous methods. The forward and reverse reactions catalyzed by this enzyme have been studied at pH 8.0 in the presence and in the absence of one product at a time, with the use of a recording fluorometer to measure changes in the concentrat...
متن کاملTransport of Proteins into Chloroplasts
The transport of proteins across the thylakoid membrane in higher plant chloroplasts is usually mediated by an amino-terminal peptide extension which is subsequently removed by a specific thylakoidal processing peptidase. We have previously shown that the reaction specificity of this enzyme is very similar to those of signal peptidases located in the endoplasmic reticulum and bacterial plasma m...
متن کاملPartitioning of malate dehydrogenase isoenzymes into glyoxysomes, mitochondria, and chloroplasts.
Malate dehydrogenase isoenzymes catalyzing the oxidation of malate to oxaloacetate are highly active enzymes in mitochondria, in peroxisomes, in chloroplasts, and in the cytosol. Determination of the primary structure of the isoenzymes has disclosed that they are encoded in different nuclear genes. All three organelle-targeted malate dehydrogenases are synthesized with an amino terminal extensi...
