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. In this article, only knots in the peptide-bonded amino acid chain are considered; knots resulting from disulfide bonds or hydrogen bonds are excluded. Knots in protein chains are rare, and the mechanisms by which they form and their functions remain subjects of experimentation and discussion<ref name="taylor2000">PMID: 10972297</ref><ref name="taylor2007">PMID: 17500039</ref><ref>PMID: 19186124</ref><ref>PMID: 19015517</ref>. Four types of knots have been found in protein chains, examples of three of which (4<sub>1</sub>, 5<sub>2</sub>, 6<sub>1</sub>) are discussed below. | A piece of string, or a protein chain, is deemed to contain a knot when pulling on the ends would leave a knot.
