WebA. Rich, F. H. C. Crick, and G. Ramachandran have shown that the rodlike collagen molecule is formed by the braiding of three polypeptide chains. Each chain, like polyproline, is twisted to form a left-handed helix having three amino acids per turn (i.e., n= -3), and these are twisted around one another to form a super helix that is right-handed. WebAug 11, 2011 · One protein family common to humans, C. parvum and in fact all eukaryotes is the group of tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation proteins (YWHA), also known as 14-3-3 proteins [8].

A superhelix is a molecular structure in which a helix is itself coiled into a helix. This is significant to both proteins and genetic material, such as overwound circular DNA. The earliest significant reference in molecular biology is from 1971, by F. B. Fuller: A geometric invariant of a space curve, the writhing number, is defined and studied. For the central curve of a twisted cord the writhing number measures the extent to which coiling of the c…

Because the length of DNA can be thousands of times that of a cell, packaging this genetic material into the cell or nucleus (in eukaryotes) is a difficult feat. Supercoiling of DNA reduces the space and allows for DNA to be packaged. In prokaryotes, plectonemic supercoils are predominant, because of the circular chromosome and relatively small amount of genetic material.
