Proceedings of the National Academy of Sciences, 2005 We report the coiled-coil structure of DNA, which is generated by the dodecanucleotide d(ATATATATATAT). The structure has been determined by single-crystal x-ray crystallography. The molecules form duplexes with single-stranded overhangs, which associate with neighbor molecules and give rise to infinite double helices in a coiled-coil conformation ...

ARCIMBOLDOon coiled coils [PDF]
Acta Crystallographica Section D Structural Biology, 2018 ARCIMBOLDOsolves the phase problem by combining the location of small model fragments usingPhaserwith density modification and autotracing usingSHELXE. Mainly helical structures constitute favourable cases, which can be solved using polyalanine helical fragments as search models. Nevertheless, the solution of coiled-coil structures is often complicated

The coiled coil‐helix‐coiled coil‐helix proteins may be redox proteins [PDF]
FEBS Letters, 2009 A number of nuclear encoded proteins are imported in to the intermembrane space of mitochondria where they adopt a coiled coil‐helix‐coiled coil‐helix (CHCH) fold. Two disulfide bonds formed by twin CX3C or CX9C motifs stabilize this fold. Some of these proteins are also characterized at their N‐termini by the presence of two additional cysteine ...

A seven-helix coiled coil [PDF]
Proceedings of the National Academy of Sciences, 2006 Coiled-coil proteins contain a characteristic seven-residue sequence repeat whose positions are designated a to g. The interacting surface between α-helices in a classical coiled coil is formed by interspersing nonpolar side chains at the a and d positions with hydrophilic residues at the flanking e and g positions.

Calculating the magnetic force of solenoid inductor wound by rectangular cross‐section wire
IET Electric Power Applications, 2021 A new semi‐analytical expression is presented based on two integrations for calculating the magnetic force of a solenoid inductor wound by rectangular cross‐section wire. The authors simplified the solenoid inductor coil to a collection of circular coils,

Evolutionary Patterns in Coiled-Coils [PDF]
Genome Biology and Evolution, 2015 Models of protein evolution are used to describe evolutionary processes, for phylogenetic analyses and homology detection. Widely used general models of protein evolution are biased toward globular domains and lack resolution to describe evolutionary processes for other protein types.

Design and optimization of printed spiral coils for wireless passive sensors
IET Wireless Sensor Systems, 2021 Monitoring physiological signals during regular life might provide many benefits including early detection of abnormalities and tracking the severities of diseases. A wireless connection between the passive sensor and the scanner eliminates the obtrusive

An optimized BSCCO/Ag resonator coil for utility use [PDF]
, 2000 AC coils made with BSCCO-2223/Ag tapes and operating in liquid nitrogen have a potential for power related applications, e.g., inductors, transformers and current limiters.

eLife, 2016 Coiled coils are the best-understood protein fold, as their backbone structure can uniquely be described by parametric equations. This level of understanding has allowed their manipulation in unprecedented detail. They do not seem a likely source of surprises, yet we describe here the unexpected formation of a new type of fiber by the simple insertion ...

Predictors of mosquito net use in Ghana
Malaria Journal, 2011 Background During the past decade the malaria control community has been successful in dramatically increasing the number of households that own mosquito nets. However, as many as half of nets already in households go unused.
