Solubilized proteins from carrot (Daucus carota L.) membranes bind calcium channel blockers and form calcium-permeable ion channels.

Proceedings of the National Academy of Sciences of the United States of America

Thuleau P, Graziana A, Ranjeva R, Schroeder JI.
PMID: 11607356
Proc Natl Acad Sci U S A. 1993 Jan 15;90(2):765-9. doi: 10.1073/pnas.90.2.765.

Calcium channels have been suggested to play a major role in the initiation of a large number of signal transduction processes in higher plant cells. However, molecular components of higher plant Ca2+ channels remain unidentified to date. Calcium channel...

K+-conducting ion channel of the chloroplast inner envelope: functional reconstitution into liposomes.

Proceedings of the National Academy of Sciences of the United States of America

Wang X, Berkowitz GA, Peters JS.
PMID: 11607404
Proc Natl Acad Sci U S A. 1993 Jun 01;90(11):4981-5. doi: 10.1073/pnas.90.11.4981.

Potassium flux between the chloroplast stroma and cytoplasm is known to be indirectly linked to H+ countertransport and, hence, stromal pH and photosynthetic capacity. The specific molecular mechanism that facilitates K+ flux across the chloroplast envelope is not known...

Photobleaching of Chlorophyll in Light-Harvesting Complex II Increases in Lipid Environment.

Frontiers in plant science

Lingvay M, Akhtar P, Sebők-Nagy K, Páli T, Lambrev PH.
PMID: 32670321
Front Plant Sci. 2020 Jun 24;11:849. doi: 10.3389/fpls.2020.00849. eCollection 2020.

Excess light causes damage to the photosynthetic apparatus of plants and algae primarily via reactive oxygen species. Singlet oxygen can be formed by interaction of chlorophyll (Chl) triplet states, especially in the Photosystem II reaction center, with oxygen. Whether...

The Mitochondrial Ascorbic Acid Transporter (MAT) from both rat liver and potato mitochondria has been reconstituted in proteoliposomes. The protein has a molecular mass in the range of 28-35 kDa and catalyzes saturable, temperature and pH dependent, unidirectional ascorbic...

Bacterial outer membrane vesicles and vaccine applications.

Frontiers in immunology

Acevedo R, Fernández S, Zayas C, Acosta A, Sarmiento ME, Ferro VA, Rosenqvist E, Campa C, Cardoso D, Garcia L, Perez JL.

Front Immunol. 2014 Mar 24;5:121. doi: 10.3389/fimmu.2014.00121. eCollection 2014.

Vaccines based on outer membrane vesicles (OMV) were developed more than 20 years ago against Neisseria meningitidis serogroup B. These nano-sized structures exhibit remarkable potential for immunomodulation of immune responses and delivery of meningococcal antigens or unrelated antigens incorporated...

Superior Efficacy and Safety of a Nonemulsive Variant of the NGcGM3/VSSP Vaccine in Advanced Breast Cancer Patients.

Breast cancer : basic and clinical research

de la Torre A, Pérez K, Vega AM, Santiesteban E, Ruiz R, Hernández L, Durrutí D, Viada CE, Sánchez L, Álvarez M, Durán Y, Moreno YG, Arencibia M, Cepeda M, Domecq M, Cabrera L, Sánchez JL, Hernández JJ, Valls AR, Fernández LE.

Breast Cancer (Auckl). 2016 Feb 18;10:5-11. doi: 10.4137/BCBCR.S32785. eCollection 2016.

NGcGM3 ganglioside is a tumor-specific antigen expressed in human breast tumors. The NGcGM3/VSSP vaccine, consisting in very small-sized proteoliposomes (VSSP) obtained by the incorporation of NGcGM3 into the outer membrane protein complex of Neisseria meningitidis, has been previously tested...

Isolation and characterization of the tricarboxylate transporter from pea mitochondria.

Plant physiology

McIntosh CA, Oliver DJ.
PMID: 16653235
Plant Physiol. 1992 Dec;100(4):2030-4. doi: 10.1104/pp.100.4.2030.

The tricarboxylate transporter was solubilized from pea (Pisum sativum) mitochondria with Triton X-114, partially purified over a hydroxylapatite column, and reconstituted in phospholipid vesicles. The proteoliposomes exchanged external [(14)C]citrate for internal citrate or malate but not for preloaded d,l-isocitrate....

Bactericidal mode of action of plantaricin C.

Applied and environmental microbiology

Gonzalez B, Glaasker E, Kunji E, Driessen A, Suarez JE, Konings WN.

Plantaricin C is a bacteriocin produced by Lactobacillus plantarum LL441 that kills sensitive cells by acting on the cytoplasmic membrane. In contrast to its lack of impact on immune cells, plantaricin C dissipates the proton motive force and inhibits...
