A crucial bottleneck in membrane protein studies, particularly G-protein coupled receptors, is the notorious difficulty of finding an optimal detergent that can solubilize them and maintain their stability and function. Here we report rapid production of 12 unique mammalian olfactory receptors using short designer lipid-like peptides as detergents. The peptides were able to solubilize and stabi...
Micellar complexes were prepared from bacteriochlorophyll a and bacteriopheophytin a with the cationic detergents, cetyltrimethyl ammonium bromide and cetylpyridinium chloride. These complexes have spectroscopic properties (absorption, circular dichroism) which are very different from the ones formed with non-ionic detergents like Triton X-100, and also with anionic detergents. Bacteriochloroph...
I t has been demonstra ted tha t in the green leaf chlorophyll is combined with protein by t rue chemical linkage. The chlorophyll-protein compound of the spinach leaf is insoluble in water and buffer solutions, bu t can be dispersed by detergents yielding bri l l iantly clear solutions. In addition to clarifying these solutions, the detergents denature the protein and change the absorption spe...
The action of synthetic detergents upon several strains of bacteriophage has been mentioned in a previous communication (Klein et al., 1945). With the exception of gamma coli phage, the bacteriophages tested were highly susceptible to the germicidal activity of the various test compounds. The gamma phage, on the other hand, proved to be resistant to the highest concentrations of the detergents ...
Enzymes are important molecules that help chemical reactions in living beings happen faster and easier. Did you know enzymes present many products used our daily lives? detergents, pets’ food own food. Sponges live the oceans need from enzymes, too. Microscopic organisms make their homes on marine sponges, these microbial partners produce sponges with nutrient digestion! These useful can also b...
The molecular mechanism of the solubilisation of phospholipid bilayers by nonionic detergents was studied by turbidity changes, carboxyfluorescein fluorescence dequenching, steady-state and time-resolved fluorescence anisotropy of DPH, lifetime measurements, ANS binding and 31P-NMR. Particular attention has been paid to the effective detergent-to-lipid ratio in the lipid phase. The disturbance ...
