A sum-product estimate in finite fields, and applications
AbstractLet A be a subset of a finite field $$ F := \mathbf{Z}/q\mathbf{Z} $$ for some prime q. If $$ |F|^{\delta} < |A| < |F|^{1-\delta} $$ for some δ > 0, then we prove the estimate $$ |A + A| +Expand

Structural basis of protein phosphatase 1 regulation
The coordinated and reciprocal action of serine/threonine (Ser/Thr) protein kinases and phosphatases produces transient phosphorylation, a fundamental regulatory mechanism for many biologicalExpand

Molecular mechanism of troponin-C function
ConclusionsThere is now a large body of evidence in support of the view that Ca2+ binding to the low affinity sites of TnC induces a movement of helices B and C away from helices A and D, thusExpand

Using a distribution function formalism, we have derived relations between the time‐dependent fluorescence polarization anistropy r(t) = [I‖(t) − I⟂(t)]/[I‖(t) + 2I⟂(t)] and the Brownian rotationalExpand

A disulfide crosslink between Cys98 of troponin-C and Cys133 of troponin-I abolishes the activity of rabbit skeletal troponin.
Various thio-reactive bifunctional crosslinkers as well as 5,5'-dithiobis(2-nitrobenzoate)-mediated disulfide bond formation were used to crosslink troponin-C and troponin-I, the Ca(2+)-binding andExpand

Immunocytochemical localization of caldesmon and calponin in chicken gizzard smooth muscle
SummaryThe distribution of caldesmon and calponin in chicken gizzard smooth muscle was investigated with immunofluorescence and immunogold electron microscopy. Immunofluorescence microscopy showedExpand

Calcium-induced movement of troponin-I relative to actin in skeletal muscle thin filaments.
The role of troponin-I (the inhibitory subunit of troponin) in the regulation by Ca2+ of skeletal muscle contraction was investigated with resonance energy transfer and photo cross-linkingExpand

Inhibition of mutant troponin C activity by an intra-domain disulphide bond
Triggering of contraction in striated muscles involves a conformational transition in the N-terminal domain of troponin C, the calcium-binding component of thin filaments. We have designed a mutantExpand

Excitation energy transfer studies on the proximity between SH1 and the adenosinetriphosphatase site in myosin subfragment 1.
Excitation energy transfer studies were carried out to determine the distance between the adenosinetriphosphatase (ATPase) site and a unique "fast-reacting" sulfhydryl (referred to as SH1) in myosinExpand
