Catch bonds
What has been your biggest error? Back at the beginning of this century, I used to say “I am going to spend the rest of my life trapped in a mitochondrion!”. This was because I was convinced that it was never going to be possible to retrieve even partial extinct genomes. Now, there are genomic sequences for many ancient humans and animals. This goes back to the famous Arthur C. Clarke quote: “W...
متن کاملCatch bonds in adhesion.
One of the most exciting discoveries in biological adhesion is the recent and counter-intuitive observation that the lifetimes of some biological adhesive bonds, called catch bonds, are enhanced by tensile mechanical force. At least two types of adhesive proteins have been shown to form catch bonds--blood proteins called selectins and a bacterial protein called FimH. Both mediate shear-enhanced...
متن کاملPolymer-based catch-bonds.
Catch-bonds refer to the counterintuitive notion that the average lifetime of a bond has a maximum at a nonzero applied force. They have been found in several ligand-receptor pairs and their origin is still a topic of debate. Here, we use coarse-grained simulations and kinetic theory to demonstrate that a multimeric protein, with self-interacting domain pairs, can display catch-bond behavior. O...
متن کاملPhenomenological and microscopic theories for catch bonds.
Lifetimes of bound states of protein complexes or biomolecule folded states typically decrease when subject to mechanical force. However, a plethora of biological systems exhibit the counter-intuitive phenomenon of catch bonding, where non-covalent bonds become stronger under externally applied forces. The quest to understand the origin of catch-bond behavior has led to the development of pheno...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
