Abstract:
Multifunctional probes are synthesized in a single step using peptide scaffold-based multifunctional single-attachment-point reagents. To obtain multifunctional probes using the methods of the invention, a substrate (e.g., a nanoparticle, polymer, antibody, protein, low molecular weight compound, drug, etc.) is reacted with a multifunctional single-attachment-point (MSAP) reagent. The MSAP reagents can include three components: (i) a peptide scaffold, (ii) a single chemically reactive group on the peptide scaffold for reaction of the MSAP with a substrate having a complementary reactive group, and (iii) multiple functional groups on the peptide scaffold. The peptide scaffold can include any number of residues; however, for ease of synthesis and reproducibility in clinical trials, it is preferred to limit the residues in the peptide to 20 or less. The reagent can be prepared to yield a predetermined stoichiometric ratio of the functional groups on the scaffold such that the probe has a fixed stoichiometric ratio of the functional groups.

Abstract:
The present invention concerns a system, comprising bacteriophages and particles comprising active agents, in which a first additional peptide is fused to proteins of the bacteriophage, the first additional peptide adheres to the surface of the particle and furthermore a second additional peptide is fused to proteins of the bacteriophage. The second additional peptide can adhere on substrate surfaces. The present invention furthermore concerns the use of the system for delayed release of active agents and also a method for production of the system. The present invention furthermore concerns a method for the selection of phage species from a combinatorial phage population.
Abstract:
Transmembrane receptors in the signaling pathways of bacterial chemotaxis systems influence cell motility by forming noncovalent complexes with the cytoplasmic signaling proteins to regulate their activity. The requirements for receptor-mediated activation of CheA, the principal kinase of the Escherichia coli chemotaxis signaling pathway, can be demonstrated using self-assembled clusters of a receptor fragment (CF) derived from the cytoplasmic domain of the aspartate receptor, Tar. Histidine-tagged Tar CF can be assembled on the surface of unilamellar vesicles via a lipid containing the Nickel-nitrilotriacetic acid moiety as a headgroup. The stability of such a complex can be controlled by the properties of the template including the size and composition, which can be used, for example, to vary the 2-dimensional concentration of receptor fragments. Surface-assembled CF is also found to serve as a substrate for receptor methylation, which is catalyzed by the receptor transferase. Since neither CheA activation nor CF methylation is observed in comparable samples in the absence of vesicles, it is concluded that surface-templating generates the organization among CF subunits required for biochemical activity.
