Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A solid coated device is disclosed that has covalently attached a coating which comprises a first layer contg. first functional groups, to which first layer functional groups is covalently attached a second, linking layer carrying second functional groups, ...
Oligomerization is a necessary step in channel formation by the bacterial toxin aerolysin. We have identified a region of aerolysin containing two tryptophans which influence the ability of the protein to oligomerize. Changing the tryptophan at position 37 ...
Template-assembled synthetic proteins (TASPs) designed to adopt globular, four-helix bundle structures form ion channels in lipid bilayers. The rationale behind this work is that a bundle of amphiphilic alpha-helices may constitute a functional pore-formin ...
For the first time, the std. free energy change, DG Deg, of a membrane-inserting protein with a leader sequence has been detd. exptl., using M13 procoat protein as an example. The partition coeff. for the distribution of the procoat protein between the aq. ...
Aerolysin is a cytolytic toxin which forms channels in the plasma membranes of eucaryotic cells. The protein is secreted by Aeromonas hydrophila as an inactive protoxin. Its stability and water solubility are conferred by its ability to dimerize. Maturatio ...
A symposium report. The total synthesis of melittin-TASP, T4-(4a26) (TASP = template assembled synthetic proteins) is described together with its structural and ion-channel forming properties in planar lipid bilayers. A voltage-dependent channel activity i ...
Template-assembled proteins (TASPs) comprising 4 peptide blocks, each of either the natural melittin sequence (melittin-TASP) or of a truncated melittin sequence (amino acid 6-26, melittin6-26-TASP), C-terminally linked to a (linear or cyclic) 10-amino aci ...
Dansyl-(Ala-Aib-Ala-Aib-Ala)3-Pro-Ala-Aib-Ala-Aib-Ala-Trp-OMe [(I), where Aib is a-aminoisobutryate] is a bent a-helical peptide which displays ion channel activity characteristic of the nicotinic acetylcholine receptor. The membrane organization, side-cha ...
The 'molten' globular conformation of a protein is compact with a native secondary structure but a poorly defined tertiary structure. Molten globular states are intermediates in protein folding and unfolding and they may be involved in the translocation or ...
Pore-forming toxins, such as colicin A, are water-soluble proteins that insert into lipid bilayers. The water-soluble structure of Colicin A is known at a high resolution and this review describes the kinetic and structural steps involved in its soluble-to ...
