I want to know the bilayer thickness (phosphate-to-phosphate or hydrocarbon region thickness) of natural membranes, especially of the plasma membrane, the Golgi and the endoplasmic reticulum. Are there any publications which can help?
Dirk
Lipid bilayer is approx 40 Angstroms thick. Surface proteins may make membranes about 45-50 Angstroms thick. Even thylakoid membranes - defficient in phospholipids and rich in non-bilayer forming monogalactosyl diglyeride lipid have lipid bilayer about the same thickness (may see papers on my researchgate page, for more).
Thanks to all!!!
i guess the reference is:
Mitra, K., I. Ubarretxena-Belandia, T. Taguchi, G. Warren, and D. M. Engelman. 2004. MODULATION OF THE BILAYER THICKNESS OF EXOCYTIC PATHWAY MEMBRANES BY MEMBRANE PROTEINS RATHER THAN CHOLESTEROL. Proc. Natl. Acad. Sci. U.S.A., 101:4083–4088.
best wishes
Does anybody know if membrane thickness is related with temperature? And is there any reference? Thanks a lot.
Dear Gregory, Coincidentally I read the paper referenced by M. D Vaidya, I recognized the exact words that were very useful for my results. If I'm not mistaken, the reference is:
Modulation of the bilayer thickness of exocytic pathway membranes by membrane proteins rather than cholesterol. Kakoli Mitra, Iban Ubarretxena-Belandia, Tomohiko Taguchi, Graham Warren and Donald M. Engelman. Current Issue. vol. 101 no. 12 Kakoli Mitra, 4083–4088, doi: 10.1073/pnas.0307332101
Best regard,
Irene
