Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...

Intrinsically disordered proteins (IDPs) do not attain a stable secondary or tertiary structure and rapidly change their ...

These groups commonly made use of multiple sequence alignments, alignment of actual and predicted secondary structures and hand–adjustments. Knowing the structure of a protein is useful for ...

A new study found that a gene recently recognized as a biomarker for Alzheimer's disease is actually a cause of it, due to its previously unknown secondary function.

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

Proteins form the structural and functional backbone of the cell, and any perturbation in their synthesis can disrupt normal ...

The rRNA molecules fold into complex secondary and tertiary structures, forming domains and motifs that are essential for ribosome function. The rRNA structures also provide binding sites for ...
