Interaction between tyrosineZ and substrate water in active photosystem II

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2006
In the field of photosynthetic water oxidation it has been under debate whether Tyrosine(Z) (Tyr(Z)) acts as a hydrogen or an electron acceptor from water. In the former concept, direct contact of Tyr(Z) with substrate water has been assumed. However, there is no direct evidence for the interaction between Tyr(Z) and substrate water in active ...

Deep Proteomic Profiles of the Antarctic Diatom Fragilariopsis Cylindrus Under Varying Iron and Manganese Conditions

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.

PhDHS Is Involved in Chloroplast Development in Petunia

open access: yesFrontiers in Plant Science, 2019
Deoxyhypusine synthase (DHS) is encoded by a nuclear gene and is the key enzyme involved in the post-translational activation of the eukaryotic translation initiation factor eIF5A. DHS plays important roles in plant growth and development.

Assembly of the precursor and processed light-harvesting chlorophyll a/b protein of Lemna into the light-harvesting complex II of barley etiochloroplasts. [PDF]

open access: yes, 1986
When the in vitro synthesized precursor of a light-harvesting chlorophyll a/b binding protein (LHCP) from Lemna gibba is imported into barley etiochloroplasts, it is processed to a single form.

Identification of senescence and death in Emiliania huxleyi and Thalassiosira pseudonana: Cell staining, chlorophyll alterations, and dimethylsulfoniopropionate (DMSP) metabolism [PDF]

open access: yes, 2012
We measured membrane permeability, hydrolytic enzyme, and caspase-like activities using fluorescent cell stains to document changes caused by nutrient exhaustion in the coccolithophore Emiliania huxleyi and the diatom Thalassiosira pseudonana, during ...

Plasticity in plant hydraulic traits: An evaluation of a common‐taxa experiment across a climatic gradient in the Western U.S.

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Due to climate change, plants are experiencing both prolonged drought events and increasingly variable water availability, prompting the need for better understanding of potential impacts on plant performance, as well as the identification of low‐water‐use plants.

Paleoproterozic Icehouses and the Evolution of Oxygen Mediating Enzymes: The Case for a Late Origin of Photosystem -- II [PDF]

open access: yes, 2008
Two major geological problems regarding the origin of oxygenic photosynthesis are: (1) identifying a source of oxygen predating biological oxygen production and capable of driving the evolution of oxygen tolerance, and (2) determining when oxygenic ...

Photophysiological and photosynthetic complex changes during iron starvation in Synechocystis sp. PCC 6803 and Synechococcus elongatus PCC 7942

open access: yes, 2013
Iron is an essential component in many protein complexes involved in photosynthesis, but environmental iron availability is often low as oxidized forms of iron are insoluble in water.

Photosynthetic Adaptation to Length of Day Is Dependent on S-Sulfocysteine Synthase Activity in the Thylakoid Lumen [PDF]

open access: yes, 2012
Arabidopsis (Arabidopsis thaliana) chloroplasts contain two O-acetyl-serine(thiol)lyase (OASTL) homologs, OAS-B, which is an authentic OASTL, and CS26, which has S-sulfocysteine synthase activity.
