We present a set of protocols showing how to use the 3DNA suite of programs to analyze, rebuild and visualize three-dimensional nucleic-acid structures. The software determines a wide range of ...

In peptides, which are smaller fragments of proteins, their helical shape arises from the repetition of specific blocks known as amino acids. These units can be arranged to create a new chiral ...

Many proteins function as helical polymers within the cell. ... Helical symmetry, ... Nucleic Acids Res. 24, 2125–2132 (1996).

Capsid proteins then assemble with nucleic acid molecules to form new viruses. ... are arranged in CPV capsids with icosahedral symmetry. A single schematic protein is outlined in red. (c) ... fC, as ...

Structures with low degrees of symmetry "The normal way to get the complex structure of proteins is to use different types of monomers, called amino acids," as Huc reports.

Peptide nucleic acid, a synthetic hybrid of protein and DNA, could form the basis of a new class of drugs—and of artificial life unlike anything found in nature For all the magnificent diversity ...

Xeno nucleic acids are essential for the development of nucleic acid-based drugs. To be effective, they need to be able to stably bind to natural RNA (a cellular single-stranded version of the DNA ...

Ken Dill and Elizaveta Guseva of Stony Brook University in New York, together with Ronald Zuckermann of the Lawrence Berkeley National Laboratory in California, presented a possible solution to the ...

His hydrophobic-polar (HP) protein-folding model treats the 20 amino acids as just two types of subunit, which he likened to different colored beads on a necklace: blue, water-loving beads (polar ...
