Peptoid helicity modulation: precise control of peptoid secondary structures via position-specific placement of chiral monomers.
The degree of peptoid helicity can be effectively modulated by position-specific incorporation of α-chiral aromatic monomers. In this study, we report the structural role of each monomer position collected from 30 comprehensive model peptoid oligomers demonstrating a meticulous manner to fine-tune peptoid secondary structures.
متن کاملStructure/function analysis of peptoid/lipitoid:DNA complexes.
Previous transfection studies of cationic peptoid polymers (N-substituted polyglycines) and cationic lipitoid polymers (peptoid-phospholipid conjugates) have shown that only the polymers which possessed a repeating (cationic, hydrophobic, hydrophobic) substituent sequence are efficient in gene transfer in vitro. To determine if there is a physical attribute of peptoid and lipitoid complexes tha...
متن کاملRibbon structure in symmetric pre-monoidal categories
Let U(g) denote the universal enveloping algebra of a Lie algebra g. We show the existence of a ribbon algebra structure in a particular deformation of U(g) which leads to a symmetric pre-monoidal category of U(g)-modules.
متن کاملStructure-determining step in the hierarchical assembly of peptoid nanosheets.
Organic two-dimensional nanomaterials are of growing importance, yet few general synthetic methods exist to produce them in high yields and to precisely functionalize them. We previously developed an efficient hierarchical supramolecular assembly route to peptoid bilayer nanosheets, where the organization of biomimetic polymer sequences is catalyzed by an air-water interface. Here we determine ...
متن کاملStructure and function of ribbon synapses.
Sensory neurons with short conduction distances can use nonregenerative, graded potentials to modulate transmitter release continuously. This mechanism can transmit information at much higher rates than spiking. Graded signaling requires a synapse to sustain high rates of exocytosis for relatively long periods, and this capacity is the special virtue of ribbon synapses. Vesicles tethered to the...
