Typically, the seven secondary structure types are reduced into three groups, helix (includes types “H,” alpha helix and “G,'' 310 helix), strand (includes “E,'' beta-ladder and “B,'' beta-bridge), and coil (all other types)

Secondary Structure • Proteins have unique structures – i e not like random mess of string • Final structure is an assembly of secondary structure elements
Protein Structure F
The final folded, 3D shape of your protein is called its tertiary structure In this second protein-folding activity, you will learn about the secondary structure of proteins This secondary structure consists of alpha helices and/or beta sheets Proteins commonly contain a combination of alpha helices and beta sheets

Protein secondary structure includes the regular polypeptide folding pat- terns such as helices sheets and turns However before we discuss these basic structural elements we must consider the geometric properties of peptide groups which underlie all higher order structures A The Peptide Group
Protein secondary structure describes the repetitive conformations of proteins and peptides There are two major forms of secondary structure the ?-helix and ?-sheet so named for the patterns of hydrogen bonds between amine hydrogen and carbonyl oxygen atoms that create the peptide backbone of a protein 1 Understanding protein
Protein secondary structure prediction Computational Aspects of Molecular Structure Teresa Przytycka PhD Assumptions in secondary structure prediction Goal: classify each residuum as alpha beta or coil Assumption: Secondary structure of a residuum is determined by the amino acid at the given position and amino acids at the neighboring
The secondary structure is the initial folding of the amino acid sequence into alpha helicesand beta sheets (Figure 2) The amino acids in an alpha helix are arranged in a helical structure about 5 angstromsin diameter Each amino acid results in a 100 degree turn in the helix; thus there are 3 6 amino acids per turn
Secondary Structure • The primary sequence or main chain of the protein must organize itself to form a compact structure This is done in an elegant fashion by forming secondary structure elements • The two most common secondary structure elements are alpha helices and beta sheets formed by repeating amino acids with the same (??) angles
