Short oxygen–halogen interactions have been known in organic chemistry since the 1950s
and recently have been exploited in the design of supramolecular assemblies. The present …

▪ Abstract The evidence showing that the self-assembly of complex RNAs occurs in discrete
transitions, each relating to the folding of sub-systems of increasing size and complexity …

… The structures are annotated for base-pairing interactions using the geometric nomenclature
of Leontis and Westhof [31]. (b) Superposition of the canonical helices (C helix) from the 3D …

… Arrays are defined as a succession of genes encoding paralogous proteins (as defined by
protein families and with a BLASTP E-value <10 -20 ) allowing a maximum of ten intervening …

… structures, as recently reviewed (Leontis & Westhof, 1998c)+ They often result from an open…
insertion of one water molecule (see, e+g+, Fig+ 3 of Westhof & Fritsch, 2000)+ We propose …

… The P2 and P9 terminal loops are shown in full detail, together with the G residues in stems
P8 and P5, respectively, with which they interact (not,e that we did not model the interaction …

Dicer is a multidomain ribonuclease that processes double-stranded RNAs (dsRNAs) to 21
nt small interfering RNAs (siRNAs) during RNA interference, and excises microRNAs from …

… In fact, I 1 and I 2 are mutually compatible, thus U/A and C/A are observed to co‐vary in the
loop E motifs of 5S rRNA and SRP ( 2 , 32 ). U/G is placed in its own group (I 3 ) because it is …

A common point of reference is needed to describe the three-dimensional arrangements of
bases and base-pairs in nucleic acid structures. The different standards used in computer …

Most continuous antigenic determinants of tobacco mosaic virus protein (TMVP), myoglobin
and lysozyme correspond to those surface regions in the protein structure, as determined by …
