Synthesis of Thylakoid Membrane Proteins by Chloroplasts Isolated from Spinach
Intact chloroplasts, purified from spinach leaves by sedimentation in density gradients of colloidal silica, incorporate labeled amino acids into at least 16 different polypeptides of the thylakoid membranes, using light as the only source of energy . The thylakoid products of chloroplast translation were visualized by subjecting membranes purified from chloroplasts labeled with [88S]methionine...
متن کاملThylakoid polypeptides of light and dark aged chloroplasts.
Spinach (Spinacia oleracea) chloroplasts were aged at 4 degrees C under red light and in the dark. The electron transport activity was monitored together with the thylakoid polypeptide patterns in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The light-induced decay of photosystem II (PSII) activity (half-life, about 4 hours) was correlated with a decrease in polypeptides with appa...
متن کاملCytogeography of Callisia section Cuthbertia (Commelinaceae)
Determining the distribution of cytotypes across the geographic distribution of polyploid complexes can provide valuable information about the evolution of biodiversity. Here, the phytogeography of cytotypes in section Cuthbertia (Small, 1903) Hunt, 1986 is investigated. A total of 436 voucher specimens was georeferenced; 133 new specimens were collected. Based on flow cytometry data, DNA conte...
متن کاملKinetic analysis of the transport of thylakoid lumenal proteins in experiments using intact chloroplasts.
The transport of the lumenal protein plastocyanin has been proposed to occur in two steps: 1) transport across the chloroplastic envelope to the stroma and 2) transport across the thylakoid membrane to the lumen where proteolytic maturation occurs. A partially processed stromal form of plastocyanin has been tentatively identified as a pathway intermediate and as the substrate for the second tra...
متن کاملRelationship between Thylakoid Membrane Fluidity and the Functioning of Pea Chloroplasts : EFFECT OF CHOLESTERYL HEMISUCCINATE.
Cholesteryl hemisuccinate has been incorporated into pea chloroplast thylakoids to investigate the relationship between fluidity and functioning of this membrane system. Levels of sterol which increased the apparent viscosity of the membrane, estimated by fluorescence polarization measurements using the lipophilic probe, 1,6-diphenyl-1,3,5 hexatriene, affected several photosynthetic processes. ...
