Pleated conformational

The most common are the alpha helixand beta pleated sheet ( see below), which are generic secondary structures held together by hydrogen bonds between the backbone peptide units. There are also less- regular but often repeated turn motifs which are used to link helices or the parallel strands of a beta sheet. Route A, retarding effect of Ser2 ( normal) phosphorylation; route B, ^ - pleated sheet- inducing effect of 8er7 ( abnor- mal). ^ - Pleated sheet formation of hyperphosphorylation [ Ser2P8er7P] and the PPII- > Jtransition induced by metal ions. The rippled sheet structure has been described for the present time only for a non- chiral polymer, i. , polyglycine ( Lotz, 1974).

The β sheet ( also β- pleated sheet) is the second form of regular secondary structure in proteins, only somewhat less common than alpha helix.
