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 review with several refs. The ultimate goal in protein de novo design is the creation of novel macromols. with tailor-made receptor, sensory, and catalytic functions. Despite considerable progress in understanding basic rules of secondary structure forma ...
In the absence of a detailed knowledge of the folding mechanism of natural proteins, the general design of polypeptide sequences with a high propensity to fold into a predetermined three dimensional structure still appears to be out of reach. The concept o ...
A review is given with 62 refs. on the art of template-based protein de novo design, with special emphasis on progress in peptide synthesis and template design and show that some fundamental questions in protein assembly, structure and function can be appr ...
The RFX DNA binding domain is a novel motif that has been conserved in a growing number of dimeric DNA-binding proteins, having diverse regulatory functions, in eukaryotic organisms ranging from yeasts to humans. To characterize this novel motif, we have p ...
This study explores the potential of MALDI-TOF MS for the mass measurement of large non-covalent protein complexes. The following non-covalent complexes have been investigated: aerolysin from Aeromonas hydrophila (335 kDa) and α-haemolysin from Staphylococ ...
The pore-forming alpha-toxin from Staphylococcus aureus is secreted as a soluble monomeric protein. In order to form a transmembrane channel, the protein has to undergo oligomerization and membrane insertion. Previous studies have shown that channel format ...
Aerolysin is a bacterial pore-forming toxin that is secreted as an inactive precursor, which is then processed at its COOH terminus and finally forms a circular heptameric ring which inserts into membranes to form a pore. We have analyzed the stability of ...
Human retinol-binding protein (RBP) is a monomeric 21-kDa protein that is currently the subject of numerous studies owing to its role in the cellular uptake and utilization of retinol. When the RBP gene is overexpressed in Escherichia coli, inclusion bodie ...
Three cyclic peptides that are Regioselectively Addressable Functionalized Templates (RAFT) for use in protein de novo design have been investigated using a combination of nmr, restrained molecular dynamics, and CD spectroscopy. These peptides contain up t ...
A series of novel, surface-active, inorganometallic complexes of osmium were synthesized and then characterized (using electrochemical techniques) as electron transfer mediators for glucose oxidase (EC 1.1.3.4, GOD) from Aspergillus niger. The mediators co ...
