Determining protein structures in cellular lamella at pseudo-atomic resolution by GisSPA

open access: yesNature Communications, 2023
Cryo-electron tomography is a major tool used to study the structure of protein complexes in situ. However, the throughput of tilt-series image data collection is still quite low.

Structure of Photosystem I Supercomplex Isolated from a Chlamydomonas reinhardtii Cytochrome b6f Temperature-Sensitive Mutant

open access: yesBiomolecules, 2023
The unicellular green alga, Chlamydomonas reinhardtii, has been widely used as a model system to study photosynthesis. Its possibility to generate and analyze specific mutants has made it an excellent tool for mechanistic and biogenesis studies.

Different adaptation strategies of two citrus scion/rootstock combinations in response to drought stress [PDF]

open access: yes, 2017
Scion/rootstock interaction is important for plant development and for breeding programs. In this context, polyploid rootstocks presented several advantages, mainly in relation to biotic and abiotic stresses.

Operation of trans-thylakoid thiol-metabolizing pathways in photosynthesis

open access: yesFrontiers in Plant Science, 2013
Thiol oxidation to disulfides and the reverse reaction, i.e. disulfide reduction to free thiols, are under the control of catalysts in vivo. Enzymatically assisted thiol-disulfide chemistry is required for the biogenesis of all energy-transducing ...

The Assembly of Super-Complexes in the Plant Chloroplast

open access: yesBiomolecules, 2021
Increasing evidence has revealed that the enzymes of several biological pathways assemble into larger supramolecular structures called super-complexes. Indeed, those such as association of the mitochondrial respiratory chain complexes play an essential ...

Chlorophyll-Protein Complexes of a Photosystem II Mutant of Maize [PDF]

open access: yesPlant Physiology, 1984
Use of the octyl beta-d-glucopyranoside solubilization procedure of Camm and Green (1980 Plant Physiol 66: 428-432) reveals that thylakoid membranes of a photosystem (PS) II-deficient maize (Zea mays L.) mutant lack two chlorophyll protein (CP) complexes associated with PSII, i.e. CPa-1 and CPa-2.

Eucalyptus ESTs corresponding to the enzyme glutamine synthetase and the protein D1, sites of action of herbicides that cause oxidative stress

open access: yesGenetics and Molecular Biology, 2005
This work was aimed at locating Eucalyptus ESTs corresponding to the GS enzyme (Glutamine Synthetase, EC = 6.3.1.2) and to the D1 protein, which are directly related to resistance to herbicides that promote oxidative stress.

N-Terminal Lipid Modification Is Required for the Stable Accumulation of CyanoQ in Synechocystis sp. PCC 6803. [PDF]

open access: yesPLoS ONE, 2016
The CyanoQ protein has been demonstrated to be a component of cyanobacterial Photosystem II (PS II), but there exist a number of outstanding questions concerning its physical association with the complex.
