Alpha helices and beta pleated sheets are the two most commonly found secondary structures in apolypeptidechain. These two structural components are the first main steps in the process of folding a polypeptide chain. Thekey differencebetween Alpha Helix and Beta Pleated Sheet is in theirstructure; ...
There are two main types of secondary structures in proteins, alpha helices and beta pleated sheets. The hydrogen bonding pattern of the amino acids in the polypeptide chain determine whether an alpha helix or a beta pleated sheet will form. Polypeptide chains can have alpha helices, beta ...
These globular proteins are composed of alpha-helices and beta-pleated sheets [6]. Despite a significant amount of amino acid sequence variability, beta-lactamases share a common overall topology (Figure 1). Sign in to download full-size image Figure 1. Crystal structures of representative ESBLs...

The primary structure of a protein (for example) is the amino acid sequence, the secondary structure is the folding of the peptide chain (e.g. alpha-helical or beta-pleated), the tertiary structure is the way in which the helices or sheets are folded or arranged to give the three-...
The HLA-DR3 molecule, shown in ribbon diagram format. Thealpha chain(yellow) and the beta chain (turquoise) assemble to form a functional heterodimeric MHC II molecule. The peptide binding cleft is flanked by alpha helices, while anti-parallel beta pleated sheets make up its floor. It is es...
This structure of a protein comes from the further bending and folding of pleated sheets and helices. A. Primary B. Secondary C. Tertiary D. Quaternary What is the protein molecule that assists in the proper folding of ...
