Membrane Protein Structure
نویسنده
چکیده
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 dielectric environments impose certain structural features to membrane proteins that we will discuss. While the lipid environment also regulates the dynamic nature of the proteins, we will not discuss them here, but refer the reader to other sources (Yeagle, 1992; Gennis, 1989).

Fouling 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 کاملComputer Aided Molecular Modeling Of Membrane Metalloprotease
Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...

In the present study we attempted to correlate the structure and function of the cry11a (72 kDa) and cry4a (135 kDa) proteins of Bacillus thuringiensis var israelensis. Homology modeling and secondary structure predictions were done to locate most probable regions for finding helices or strands in these proteins. The JPRED (JPRED consensus secondary structure prediction server) secondary struct...
متن کاملProtein and Lactose Separation by Modified Ultrafiltration Membrane using Layer by Layer Technique
Layer-by-Layer (LbL) is a method which can be used for nanoscale coating and surface functionalization of a material. LbL technique mainly uses the electrostatic attracting between charged materials (polyelectrolytes, nanoparticles, etc.) and an oppositely charged surface. In this study, protein separation (BSA) from lactose solution was carried out using the LbL self-assembly method, which was...
متن کاملThe Coating Effect of PANI/Silver on Performance of Polysulfone Membrane Toward Protein Separation
The effects of different coating time of PANI/Silver onto polysulfone (PSf) membrane surface were investigated based on the morphology, contact angle, surface roughness and rejection towards BSA, pepsin and trypsin. The membrane was prepared by employing the pressure deposition method toward phase inversed membrane. Thus, PANI particles were forced to adhere on membrane surface by pressure driv...
