Enzymatic synthesis and decarboxylation of phosphatidylserine in Tetrahymena pyriformis [PDF]
Cell-free extracts of the protozoan Tetrahymena pyriformis have been found to catalyze the following reactions: Phosphatidylethanolamine+L-Serine⇌Phosphatidylserine+EthanolaminePhosphatidylserine→Phosphatidylethanolamine+CO2Net:L-Serine→Ethanolamine ...

Role of Calcium in Phosphatidylserine Externalisation in Red Blood Cells from Sickle Cell Patients [PDF]
Phosphatidylserine exposure occurs in red blood cells (RBCs) from sickle cell disease (SCD) patients and is increased by deoxygenation. The mechanisms responsible remain unclear.

On the coordination of La3+ by phosphatidylserine [PDF]
In a recent study by Bentz, J., D. Alford, J. Cohen, and N. Düzgünes (1988. Biophys. J. 53:593-607), La3+ was found to be more effective than Ca2+ in causing nonleaky fusion of phosphatidylserine vesicles. It was proposed that this difference in fusion efficiency may be due, in part, to a difference in coordination of the two cations. That is, Ca2+ was

Adoptive therapy with genetically engineered T cells offers potential for infectious disease treatment in immunocompromised persons. HIV/simian immunodeficiency virus (SIV)-infected cells express phosphatidylserine (PS) early post infection.

Phosphatidylserine, a death knell [PDF]
Virtually every cell in the body restricts phosphatidylserine (PS) to the inner leaflet of the plasma membrane by energy-dependent transport from the outer to the inner leaflet of the bilayer. Apoptotic cells of all types rapidly randomize the asymmetric distribution, bringing PS to the surface where it serves as a signal for phagocytosis.

Inhibition of phosphatidylserine recognition heightens the immunogenicity of irradiated lymphoma cells in vivo [PDF]
Strategies to enhance the immunogenicity of tumors are urgently needed. Although vaccination with irradiated dying lymphoma cells recruits a tumor-specific immune response, its efficiency as immunogen is poor.

ATP11C is a major flippase in human erythrocytes and its defect causes congenital hemolytic anemia
Phosphatidylserine is localized exclusively to the inner leaflet of the membrane lipid bilayer of most cells, including erythrocytes. This asymmetric distribution is critical for the survival of erythrocytes in circulation since externalized ...

Phosphatidylserine decarboxylase from Clostridium butyricum.
Phosphatidylserine decarboxylase activity has been characterized in membrane preparations from Clostridium butyricum ATCC 19398. A particulate fraction was shown to catalyze the formation of phosphatidylethanolamine and plasmenylethanolamine when ...

Glu- and Lys-forms of plasminogen differentially affect phosphatidylserine exposure on the platelet surface [PDF]
Plasminogen/plasmin system is known for its ability to support hemostatic balance of blood. However, plasminogen may be considered as an adhesive ligand and in this way could affect the functioning of blood cells. We showed that exogenous Lys-plasminogen,
