Membrane Structure and Function
An understanding of the biochemical basis of membrane function is an important goal of present day biology. In this paper, a biochemical approach to the problem of the specific transport of sugars across the membrane of Escherichia coli is discussed. A new biochemical model for lactose transport system in this organism is presented, in which a specific membrane protein (M protein) plays the rol...
متن کاملProgress in the analysis of membrane protein structure and function.
Structural information on membrane proteins is sparse, yet they represent an important class of proteins that is encoded by about 30% of all genes. Progress has primarily been achieved with bacterial proteins, but efforts to solve the structure of eukaryotic membrane proteins are also increasing. Most of the structures currently available have been obtained by exploiting the power of X-ray crys...
متن کاملFouling mechanisms during protein microfiltration: The effects of protein structure and filtration pressure on polypropylene microporous membrane performance
A polypropylene microporous membrane (PPMM) was fabricated by thermally induced phase separation (TIPS) method. The effects of protein size and structure as well as filtration pressure on the membrane performance and fouling mechanisms were investigated using two different proteins, bovine serum albumin (BSA) and collagen, in dead-end filtration setup. Obtained results showed that, for each pro...
متن کاملMembrane Protein Structure
Membrane proteins reside in a highly asymmetric environment compared to their cytosolic counterparts which gives them unique properties. Rather than being in a homogeneous aqueous solvent, the "solvent" that surrounds membrane proteins consists of the aqueous region outside the membrane, the ionic region of the membrane surface and the oily region of the membrane interior. These differing diele...
متن کاملLipid-protein interactions as determinants of membrane protein structure and function.
To determine how the lipid environment affects membrane protein structure and function, strains of Escherichia coli were developed in which normal phospholipid composition can be altered or foreign lipids can be introduced. The properties of LacY (lactose permease) were investigated as a function of lipid environment. Assembly of LacY in membranes lacking PE (phosphatidylethanolamine) results i...
