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.

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.

Endoscopic Ultrasound-Guided Angiotherapy for Gastric Varices—A Small Retrospective Study
Journal of Digestive Endoscopy, 2020 Introduction Conventional n-butyl-cyanoacrylate (CYA) recommended for secondary prophylaxis of gastric varices (GV) is associated with significant rebleeding and glue embolism.

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 ...

Effect of Microstructures on Yield Strength in Hot-Stamped Steel Sheet
MATEC Web of Conferences, 2015 For automotive structural parts, hot stamping is being increasingly used because of the need for both higher fuel efficiency and crashworthiness. The yield strength of hot-stamped steel sheet is lower than that of water-quenched steel sheet.
