Design of printed circuit coils [PDF]
, 1969 Spiral-like coil is printed with several extra turns which increase the realizable coil inductance. Included are shorting connections which not only short the extra turns, but also short out several turns of the main body.

Design of a heterotetrameric coiled coil [PDF]
Protein Science, 2009 AbstractWe have successfully designed a simple peptide sequence that forms highly stable coiled‐coil heterotetramers. Our model system is based on the GCN4‐pLI parallel coiled‐coil tetramer, first described by Kim and coworkers (Harbury et al., Science 1993;262:1401–1407). We introduced glutamates at all of the e and c heptad positions of one sequence (

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Structural specificity in coiled-coil interactions [PDF]
Current Opinion in Structural Biology, 2008 Coiled coils have a rich history in the field of protein design and engineering. Novel structures, such as the first seven-helix coiled coil, continue to provide surprises and insights. Large-scale datasets quantifying the influence of systematic mutations on coiled-coil stability are a valuable new asset to the area.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
