Proposed Article Title: Knots in Proteins

Insert caption here

Drag the structure with the mouse to rotate

A piece of string, or a protein chain, is deemed to contain a knot when pulling on the ends would leave a knot. When the ends of most folded protein chains are "pulled", they resolve to a straight chain between the pulled ends: no knot remains. Knots in protein chains are rare, and the mechanisms by which they form and their functions remain subjects of speculation[1]. A dramatic example, discovered in 2000[1], is illustrated here.

noncovalent pseudoknots [2]
