Protein extended conformation
Did you know?
Protein secondary structure is the local spatial conformation of the polypeptide backbone excluding the side chains. The two most common secondary structural elements are alpha helices and beta sheets, though beta turns and omega loops occur as well. Secondary structure elements typically … Visa mer The most common secondary structures are alpha helices and beta sheets. Other helices, such as the 310 helix and π helix, are calculated to have energetically favorable hydrogen-bonding patterns but are rarely observed in … Visa mer Both protein and nucleic acid secondary structures can be used to aid in multiple sequence alignment. These alignments can be made more … Visa mer • Biology portal • Folding (chemistry) • Nucleic acid secondary structure • Translation Visa mer • NetSurfP – Secondary Structure and Surface Accessibility predictor • PROF • ScrewFit Visa mer The rough secondary-structure content of a biopolymer (e.g., "this protein is 40% α-helix and 20% β-sheet.") can be estimated spectroscopically. For proteins, a common method is far … Visa mer Predicting protein tertiary structure from only its amino sequence is a very challenging problem (see protein structure prediction), but using the simpler secondary structure definitions is more tractable. Early methods of … Visa mer • Branden C, Tooze J (1999). Introduction to protein structure (2nd ed.). New York: Garland Science. ISBN 978-0815323051. • Pauling L, Corey RB (1951). "Configurations of Polypeptide Chains With Favored Orientations Around Single Bonds: Two New Pleated Sheets". … Visa mer The beta sheet, (β-sheet) (also β-pleated sheet) is a common motif of the regular protein secondary structure. Beta sheets consist of beta strands (β-strands) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet. A β-strand is a stretch of polypeptide chain typically 3 to 10 amino acids long with backbone in an extended conformation. The supramolecular association of β-sheets has been implicated in the formation of the fibrils and protein …
