Plant Carbonic Anhydrases, their Role in Stress Defense and Possible Practical Use [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2018
The review presents data on the distribution of carbonic anhydrases in photosynthetic organisms and their location in cellular compartments. The functions of carbonic anhydrases to provide a high photosynthesis rate as well as their participation in ...

Phosphoproteins and protein-kinase activity in isolated envelopes of pea (Pisum sativum L.) chloroplasts [PDF]

open access: yes, 1985
A protein kinase was found in envelope membranes of purified pea (Pisum sativum L.) chloroplasts. Separation of the two envelope membranes showed that most of the enzyme activity was localized in the outer envelope.

Adenylate effects on protein phosphorylation in the interenvelope lumen of pea chloroplasts [PDF]

open access: yes, 1989
A 64-kilodalton (kDa) protein, situated in the lumen between the inner and outer envelopes of pea (Pisum sativum L.) chloroplasts (Soll and Bennett 1988, Eur. J.

Contrasting Responses to Stress Displayed by Tobacco Overexpressing an Algal Plastid Terminal Oxidase in the Chloroplast

open access: yesFrontiers in Plant Science, 2020
The plastid terminal oxidase (PTOX) – an interfacial diiron carboxylate protein found in the thylakoid membranes of chloroplasts – oxidizes plastoquinol and reduces molecular oxygen to water. It is believed to play a physiologically important role in the

Fatty acid composition and cpDNA content in Arabidopsis thaliana mutants deprived of EGY1 protease

open access: yesPhotosynthetica, 2021
EGY1 (ethylene-dependent gravitropism-deficient and yellow-green 1) is an intramembrane metalloprotease located in chloroplasts, involved in many diverse processes including chloroplast development, chlorophyll biosynthesis, and the ethylene-dependent ...

Characterization of the protein import apparatus in isolated outer envelopes of chloroplasts [PDF]

open access: yes, 1991
Isolated outer envelope membrane from pea (Pisum sativum L.) chloroplasts can be used in vitro to study binding and partial translocation of precursor proteins destined for the inside of the organelle.

Outer envelope membranes from chloroplasts are isolated as right-side-out vesicles [PDF]

open access: yes, 1992
Outer envelope membranes were isolated from purified chloroplasts of pea leaves. The sidedness of the vesicles was analyzed by (i) aqueous polymer-two phase partitioning, (ii) the effect of limited proteolysis on the outer-envelope proteins (OEP) 86 and ...

A guanosine 5′-triphosphate-dependent protein kinase is localized in the outer envelope membrane of pea chloroplasts [PDF]

open access: yes, 1988
A guanosine 5-triphosphate (GTP)-dependent protein kinase was detected in preparations of outer chloroplast envelope membranes of pea (Pisum sativum L.) chloroplasts.

Pigments and ultrastructural peculiaries of cell organelles of fern Polystichum aculeatum (L.) Roth. at different stages of development

open access: yesБіологічні студії, 2017
Qualitative and quantitative content of photosynthetic pigments in fronds of P aculeatum sporophyte at different stages of ontogeny was determined. The maximum content of photosynthetic pigments was registered at the stages of spore fructification and ...
