Evidence for the role of surface-exposed segments of the light-harvesting complex in cation-mediated control of chloroplast structure and function☆
TLDR
Cation-induced changes in room temperature fluorescence intensity and low temperature chlorophyll fluorescence emission spectra, and cation regulation of the quantum yield of photosystem I and II partial reactions at limiting light were lost following the trypsin-induced alteration of the LHC.About:

Mechanisms of photoprotection and nonphotochemical quenching in pea light-harvesting complex at 2.5 Å resolution
TL;DR: A simple mechanism for the xanthophyll‐related, slow component of nonphotochemical quenching in LHC‐II is proposed, by which excess energy is transferred to a zeaxanthin replacing violAXanthin in its binding site, and dissipated as heat.
Journal ArticleDOI
Chloroplast protein phosphorylation couples plastoquinone redox state to distribution of excitation energy between photosystems
John F. Allen,John F. Allen,John Bennett,Katherine E. Steinback,Katherine E. Steinback,Charles J. Arntzen,Charles J. Arntzen +6 more
TL;DR: In photosynthetic membranes isolated from pea leaves, the redox state of the plastoquinone pool controls both the level of phosphorylation of the chloroplast light-harvesting pigment–protein complex (LHC) and distribution of absorbed excitation energy between the two photosystems.
Journal ArticleDOI
Influence of Surface Charges on Thylakoid Structure and Function
TL;DR: This paper presents a meta-analysis of 9-Amino Acridine technique and its applications in particle electrophoresis and concludes that the technique can be applied to surface charge determination as well as other determinants of surface attraction.
Journal ArticleDOI
Regulation of chloroplast membrane function: protein phosphorylation changes the spatial organization of membrane components.
L A Staehelin,Charles J. Arntzen +1 more
TL;DR: This regulatory mechanism provides a rationale for the finding that the two photosystems are physically separated in chloroplast membranes (PS II in appressed, grana membranes, and PS I in nonappressed, stroma membranes).

Cleavage of Structural Proteins during the Assembly of the Head of Bacteriophage T4
TL;DR: Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products.

Cleavage of structural proteins during the assemble of the head of bacterio-phage T4
TL;DR: Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products as mentioned in this paper.

The reliability of molecular weight determinations by dodecyl sulfate-polyacrylamide gel electrophoresis
Klaus Weber,Mary Osborn +1 more
TL;DR: The results show that the polyacrylamide gel electrophoresis method can be used with great confidence to determine the molecular weights of polypeptide chains for a wide variety of proteins.
Journal ArticleDOI
A low-viscosity epoxy resin embedding medium for electron microscopy.
TL;DR: A low-viscosity embedding medium based on ERL-4206 is recommended for use in electron microscopy and has a long pot life of several days and infiltrates readily because of its low viscosity.
Journal ArticleDOI
Absorption of light by chlorophyll solutions
TL;DR: This paper deals with the estimation of chlorophyll in plant extracts by application of absorption coefficients of the isolated solid chlorophylla components, and the question of artifacts is automatically clarified.
