Thermal stability of membrane-bound proteins
nanoDSF, the miniaturized differential scanning fluorimetry technology, is a revolutionary method to determine the thermostability of proteins by following changes in their intrinsic fluorescence. In this comparative study, the Prometheus NT.48 was used to determine the thermal stability of the membrane esterase PA2949 from Pseudomonas aeruginosa in presence of various detergents. The detergent...
متن کاملStructural prediction of membrane-bound proteins.
A prediction algorithm based on physical characteristics of the twenty amino acids and refined by comparison to the proposed bacteriorhodopsin structure was devised to delineate likely membrane-buried regions in the primary sequences of proteins known to interact with the lipid bilayer. Application of the method to the sequence of the carboxyl terminal one-third of bovine rhodopsin predicted a ...
متن کاملStructural analysis of membrane-bound retrovirus capsid proteins.
We have developed a system for analysis of histidine-tagged (His-tagged) retrovirus core (Gag) proteins, assembled in vitro on lipid monolayers consisting of egg phosphatidylcholine (PC) plus the novel lipid DHGN. DHGN was shown to chelate nickel by atomic absorption spectrometry, and DHGN-containing monolayers specifically bound gold conjugates of His-tagged proteins. Using PC + DHGN monolayer...
متن کاملLabel-free detection of clustering of membrane-bound proteins.
We report a new and label-free method to detect and characterize the clustering of membrane-bound proteins and, by extension, the lateral segregation of nanosized particles adsorbed to planar surfaces in liquid environment. The method exploits the contrast between two different mass and surface sensitive detection methods, quartz crystal microbalance with dissipation monitoring and ellipsometry...
متن کاملThe carboxylmethylation of cerebral membrane-bound proteins increases with age.
Recently, we have characterized a membrane-bound (mb) component of brain protein carboxylmethyltransferase II (PCMT) which effectively carboxylmethylates endogenous mb methyl-accepting proteins (MAPs). (Neurochem. Int., 10 (1987) 155). We have also shown that exposing mb-MAPs to mild alkali leads to a marked increase in their recognition by PCMT. Since one of the likely consequences of the alka...
