Fusion-protein-assisted protein crystallization.
Fusion proteins can be used directly in protein crystallization to assist crystallization in at least two different ways. In one approach, the `heterologous fusion-protein approach', the fusion partner can provide additional surface area to promote crystal contact formation. In another approach, the `fusion of interacting proteins approach', protein assemblies can be stabilized by covalently li...
متن کاملCrystallization of Membrane Protein Nanoparticles
The self-assembly of membrane proteins from solution into two-dimensional crystals is studied numerically using a continuum model proposed by Talanquer and Oxtoby (J. Chem. Phys. 109, 223 (1998)). Although the mean field theory presented here is only qualitatively accurate in two dimensions, we obtain the main features of the crystal nucleation process, such as the nucleation free energy barrie...
متن کاملA pedestrian guide to membrane protein crystallization.
Membrane protein structural biology is a frontier area of modern biomedical research. Twenty to thirty-five percent of the proteins encoded by an organism's genome are integral membrane proteins. Integral membrane proteins, such as channels, transporters, and receptors, are critical components of many fundamental biological processes. Also, many integral membrane proteins are important in biome...
متن کاملLytU-SH3b fusion protein as a novel and efficient enzybiotic against methicillin-resistant Staphylococcus aureus
Methicillin-resistant Staphylococcus aureus (MRSA) is a challenging infectious agent worldwide. The ever growing antibiotic resistance has made the researchers to look for new anti-staphylococcal agents. Autolysins are staphylococcal enzymes that lyse bacterial cell wall for cell division. Autolysins can be used as novel enzybiotics (enzymes have antibiotic effects) for staphylococcal ...
متن کاملLysine methylation as a routine rescue strategy for protein crystallization.
Crystallization remains a critical step in X-ray structure determination. Because it is not generally possible to rationally predict crystallization conditions, commercial screens have been developed which sample a wide range of crystallization space. While this approach has proved successful in many cases, a significant number of proteins fail to crystallize despite being soluble and monodispe...
