as these are the dominant lipids in the inner leaflet of bacterial OM75. The symmetric incorporation of DMPE into DMPG liposomes slows folding, consistent with symmetric DMPC/DMPE mixes33. However, we have shown that this inhibition can be partially overcome by introducing DMPE asymmetrically into ...
All major biological macromolecules (DNA, RNA, proteins and lipids) undergo enzyme-catalysed covalent modifications that impact their structure, function and stability. A variety of covalent modifications of RNA have been identified and demonstrated to affect RNA stability and translation to proteins; the...
The intrinsic fluorescence of tyrosine was used to probe the binding of lipids to HvLTP1.1. However, at first, the solvent exposed Tyr91 had to be removed from HvLTP1.1 by cleavage with carboxypeptidase. The Kdfor binding to LMPC for this truncated form of HvLTP1.1 was close to 10−6M ...

Transporters and channels facilitate the translocation of small molecules such as ions, water, glucose, lactate, vitamin, and neurotransmitters, as well as macromolecules such as lipids and proteins. They play important roles in maintainin...
cannot pass. The membranes are fused by tight associations of two types of specializedintegralmembrane proteins, in turn repelling large water-soluble molecules. Ininvertebratesthis function is provided by septate junctions, in which the proteins of the membrane rather than the lipids form the seal....
Lipid droplets (LDs), which are active organelles, derive from the monolayer membrane of the endoplasmic reticulum and encapsulate neutral lipids internally. LD-associated proteins like RAB, those in the PLIN family, and those in the CIDE family particip

Lipid droplets (LDs) are lipid storage organelles primarily functioning in cellular energy metabolism1. LD biogenesis occurs at the endoplasmic reticulum (ER) membrane during energy rich or stress conditions. LD biogenesis starts with the synthesis of neutral lipids, such as triacylglycerols (TG) or ...
