Single-molecule imaging reveals the concerted release of myosin from regulated thin filaments
eLife, 2021 Regulated thin filaments (RTFs) tightly control striated muscle contraction through calcium binding to troponin, which enables tropomyosin to expose myosin-binding sites on actin. Myosin binding holds tropomyosin in an open position, exposing more myosin-

Propagation of melting cooperativity along the phosphodiester backbone of DNA [PDF]
, 2003 The role of the DNA phosphodiester backbone in the transfer of melting cooperativity between two helical domains was experimentally addressed with a helix-bulge-helix DNA model, in which the bulge consisted of a varying number of either conformationally ...

Probing Edge/Support Electronic Cooperativity in Single Edge Fe/Co6Se8 Clusters [PDF]
, 2022 This study provides insights into the electronic structure of an atomically precise Fe/Co6Se8 cluster and the extent of redox cooperativity between the Fe active site and the non-innocent Co6Se8 support. Chemical oxidation studies enable the isolation of

IC2 participates in the cooperative activation of outer arm dynein densely attached to microtubules
Cell Structure and Function, 2023 Ciliary outer-arm dynein (OAD) consists of heavy chains (HCs), intermediate chains (ICs), and light chains (LCs), of which HCs are the motor proteins that produce force.

Self-Sorting Governed by Chelate Cooperativity [PDF]
, 2022 Self-sorting phenomena are the basis of manifold relevant (bio)chemical processes where a set of molecules is able to interact with no interference from other sets and are ruled by a number of codes that are programmed in molecular structures.

Understanding the origins of strong multivalent cooperativity [PDF]
, 2019 This thesis presents a combined experimental and computational evaluation of chelate cooperativity. The principal result from the thesis is that host-guest design cannot be limited to chemical intuition.

Molecules, 2015 A theoretical study of the beryllium bonds in BeR2:C6X6 (R = H, F, Cl and X = H and F) has been carried out by means of MP2/aug′-cc-pVDZ computational methods. In addition, the ternary complexes BeR2:C6X6:Y− (Y = Cl and Br) have been analyzed. Geometric,

Sequencing and Cooperation [PDF]
Operations Research, 1994 In machine scheduling the first problem is to find a timetable that is optimal with respect to some efficiency criterion. If the jobs come from different clients the solution of the optimization problem is not the end of the story. In addition, we have to decide how the minimal total cost must be distributed among the parties involved.

Cooperativity in micellar solubilization [PDF]
, 2021 Sudden onset of solubilization is observed widely around or below the critical micelle concentration (CMC) of surfactants. It has also been reported that micellization is induced by the solutes even below CMC and the solubilized solute increases the ...
