Protein fold class - Wikipedia
α+β proteins are a class of structural domains in which the secondary structure is composed of α-helices and β-strands that occur separately along the backbone. The β-strands are therefore …
Protein secondary structure - Wikipedia
Protein secondary structure is the local spatial conformation of the polypeptide backbone excluding the side chains. [1] The two most common secondary structural elements are alpha …
4.5: Protein with Alpha, Alpha-Beta, Beta and Little Secondary ...
Alpha/Beta proteins. These are the most common class and contain many beta-alpha-beta motifs with mostly parallel beta strands surrounded by alpha helices. Again, these proteins have …
4.4: Secondary Structural Motifs and Domains - Biology LibreTexts
Beta-Alpha-Beta. The motif is a common way to connect two parallel beta strands as compared to beta hairpins, which are used to connect antiparallel beta strands. Figure \(\PageIndex{12}\) …
4.2: Secondary Structure and Loops - Biology LibreTexts
About 50% of the amino acids in a globular (spherical) protein are in regular secondary structure (alpha or beta). The amino acids in helices and beta strands are connected by stretches of …
