Assembly of Lipids into Membranes in Acanthamoeba Palestinensis
The membranes of Acanthamoeba palestinensis were studied by examination in fixed cells, and then by following the movements of glycerol-(3)H-labeled phospholipids by cell fractionation. Two previously undescribed structures were observed: collapsed cytoplasmic vesicles of cup shape, and plaques in food vacuole and plasma membrane similar in size to the collapsed vesicles. It appeared that the p...
متن کاملASSEMBLY OF LIPIDS INTO MEMBRANES IN ACANTHAMOEBA PALESTINENSIS I. Observations on the Specificity and Stability of Choline-1 4C and Glycerol-3H as Labels for Membrane Phospholipids
In order to determine the feasibility of using radioactive precursors as markers for membrane phospholipids in Acanthamoeba palestinensis, the characteristics of phospholipids labeled with choline-14 C and glycerol-3H were examined . Choline-14 C was found to be a specific label for phosphatidyl choline . There was a turnover of the radioactive moiety of phosphatidyl choline at a rate that vari...
متن کاملLipids of Acanthamoeba Castellanii
The lipids of Acanthamoeba castellanii (Neff) consist of 52% neutral lipids and 48% polar lipids. Triglycerides account for 75% and free sterols for 17% of the neutral lipids. The major phospholipids are phosphatidylcholine (45%), phosphatidylethanolamine (33%), phosphatidylserine (10%), a phosphoinositide (6%), and diphosphatidylglycerol (4%). The phosphoinositide is unique in that it contains...
متن کاملLipid assembly into cell membranes
A fundamental problem of cell biology and biochemistry is the elucidation of the mechanisms by which the specific components of subcellular membranes are assembled into mature organelles. The major components of all cell membranes are lipids and proteins. The presence of discrete structural motifs contained in the primary sequence of proteins directs a large number of post-translational process...
متن کاملMolecular Identification and Sequencing of Mannose Binding Protein (MBP) Gene of Acanthamoeba palestinensis
BACKGROUND Acanthamoeba keratitis develops by pathogenic Acanthamoeba such as A. palestinensis. Indeed this species is one of the known causative agents of amoebic keratitis in Iran. Mannose Binding Protein (MBP) is the main pathogenicity factors for developing this sight threatening disease. We aimed to characterize MBP gene in pathogenic Acanthamoeba isolates such as A. palestinensis. METHO...
