Interlocked porphyrin switches.
We describe the synthesis of a series of interlocked structures from porphyrin-glycoluril cage compounds and bis(olefin)-terminated viologens by an olefin-metathesis protocol. The length of the chain connecting the olefin substituents with the viologen has a marked effect on the products of the ring-closure reaction. Long chains give [2]- and [3]catenane structures, whereas short chains give a ...
متن کاملIon-mediated conformational switches
Molecular switches are ubiquitous in Nature and provide the basis of many forms of transport and signalling. Single synthetic molecules that change conformation, and thus function, reversibly in a stimulus-dependent manner are of great interest not only to chemists but society in general; myriad applications exist in storage, display, sensing and medicine. Here we describe recent developments i...
متن کاملSubassembly Generation via Mechanical Conformational Switches
A question is posed on how a particular subassembly sequence is generated in randomized assembly. An extended design of mechanical conformational switches [16] is proposed that can encode several subassembly sequences. A particular subassembly sequence is generated due to conformational changes of parts during one-dimensional randomized assembly. The optimal subassembly sequence that maximizes ...
متن کاملProtein conformational switches: from nature to design.
Protein conformational switches alter their shape upon receiving an input signal, such as ligand binding, chemical modification, or change in environment. The apparent simplicity of this transformation--which can be carried out by a molecule as small as a thousand atoms or so--belies its critical importance to the life of the cell as well as its capacity for engineering by humans. In the realm ...
متن کاملAutomated Optimal Design of Mechanical Conformational Switches
Bacteriophage viruses spontaneously self-assemble in the presence of their component parts (certain protein molecules). It is believed that conformational switches, interacting chemical bonding sites that allow tentative incorrect bonds, facilitate this randomized assembly process. A onedimensional conformational switch is proposed and used to study the randomized assembly of mechanical parts. ...
