WebDSSP-web. DSSP-web is a tool to assign the secondary structure in a protein by DSSP program [Kabsch and Sander, 1983] based on the analysis of backbone dihedral angles … WebThe number of residues with each secondary structure type and the total secondary structure (-sss) count as a function of time are also written to file (-sc). Solvent accessible surface (SAS) per residue can be calculated, both in absolute values (A^2) and in fractions of the maximal accessible surface of a residue.
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 natural proteins except at the ends of α helices due to unfavorable backbone packing in the center of the helix. Other extended structures such as the polyproline helix and alpha … WebJul 1, 2004 · Several automatic tools for secondary structure assignment from known atomic coordinates are available [reviewed in ]. The most widely used method, DSSP , defines secondary structure elements as repeating elementary hydrogen bonded patterns. Hydrogen bonds between peptide units are assigned if the electrostatic interaction …

Generally speaking, … WebJan 21, 2024 · Video DescriptionIn this video, we briefly describe the dihedral angle and main chain hydrogen bonding criteria for different secondary structural elements a...
The DSSP algorithm is the standard method for assigning secondary structure to the amino acids of a protein, given the atomic-resolution coordinates of the protein. The abbreviation is only mentioned once in the 1983 paper describing this algorithm, where it is the name of the Pascal program that … See more DSSP begins by identifying the intra-backbone hydrogen bonds of the protein using a purely electrostatic definition, assuming partial charges of −0.42 e and +0.20 e to the carbonyl oxygen and amide hydrogen … See more • STRIDE (algorithm) an alternative algorithm • Chris Sander (scientist) See more • DSSP Analysis tool • Continuous DSSP tool See more In the original DSSP algorithm, residues were preferentially assigned to α helices, rather than π helices. In 2011, it was shown that DSSP failed to annotate many "cryptic" π helices, … See more In 2002, a continuous DSSP assignment was developed by introducing multiple hydrogen bond thresholds, where the new assignment was found to correlate with protein motion.
