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 ...

Balloon-Catheter Buddy Technique for Coiling of Very Small Aneurysm
Journal of Clinical Interventional Radiology ISVIR, 2022 The catheter movement and stability in coiling of very small aneurysms is challenging. We describe a technique for controlled catheter movement and successful coiling of a very small aneurysm.

Anterior Communicating Artery Aneurysms: Anatomical Considerations and Microsurgical Strategies
Frontiers in Neurology, 2020 Anterior communicating artery aneurysms account for 23–40% of ruptured intracranial aneurysms and 12–15% of unruptured aneurysms and are the most common intracranial ruptured or unruptured aneurysms.

Initial experience with aneurysm coiling in Nepal
Nepal Journal of Neuroscience, 2018 The aim of this study is to show the result of aneurysm coiling despite the difficulty in initiating neurointervention in Nepal. It is a retrospective study where only aneurysm that has undergone coiling are taken from 2017 to 2018.A total of eleven ...

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.
