The signal recognition particle (SRP) and its receptor compose a universally conserved and
essential cellular machinery that couples the synthesis of nascent proteins to their proper …

Early on, comparisons of known SPs indicated that they typically have three distinct domains
(Fig. 1): an amino-terminal positively charged region (n-region, 1-5 residues long); a central …

Phospholipids play multiple roles in cells by establishing the permeability barrier for cells
and cell organelles, by providing the matrix for the assembly and function of a wide variety of …

During the past few years, considerable progress has been made in understanding how
plants protect themselves against oxidative stress. Genes encoding plant antioxidant …

The unifying feature of all proteins that are transported out of the cytoplasm of gram-negative
bacteria by the general secretory pathway (GSP) is the presence of a long stretch of …

▪ Abstract The contribution of membrane lipids, particularly the level of unsaturation of fatty
acids, to chilling sensitivity of plants has been intensively discussed for many years. We …

Determining the chemical composition of biological materials is paramount to the study of
natural phenomena. Here, we describe the composition of model gram-negative outer …

Membranes lipids are one of the most adaptable molecules in response to perturbations.
Even subtle changes of the composition of acyl chains or head groups can alter the packing …

Electrostatic phenomena play a crucial role in many biological processes. For membranes
they are signifi-

Most proteins are secreted from bacteria by the interaction of the cytoplasmic SecA ATPase
with a membrane channel, formed by the heterotrimeric SecY complex. Here we report the …
