sDFIRE: Sequence‐specific statistical energy function for protein structure prediction by decoy selections

Abstract: An important unsolved problem in molecular and structural biology is the protein folding and structure prediction problem. One major bottleneck for solving this is the lack of an accurate energy to discriminate near-native conformations against other possible conformations. Here we have developed sDFIRE energy function, which is an optimized linear combination of DFIRE (the Distance-scaled Finite Ideal gas Reference state based Energy), the orientation dependent (polar-polar and polar-nonpolar) statistical pot… Show more

“…Specifically, we used two commonly employed decoy sets: the I-TASSER Decoy Set-II generated by the Zhang lab [ 33 ] and the Rosetta decoy set by the Baker lab [ 34 ]. These have been broadly used to test a variety of scoring methods [ 35 42 ]. The decoys in these two datasets were generated differently, and therefore represent different test cases for a scoring function.…”

“…The energy of interaction between protein residues ensures protein structural stability, and the energy contribution of residue interactions can be approximated by an energy function extracted from known structures ( Hoque et al, 2016 ; Mishra et al, 2016 ). Dosztanyi et al (2005) performed the least square fit of the contact energy derived from the primary sequences of 674 proteins to the tertiary structures of 785 proteins and constructed the RCEM matrix, a 20×20 dimensional matrix with rows and columns representing the 20 standard amino acids.…”

“…The profiles of unpaired/paired bases generated by SHAPE and DMS experiments have already been used for improving secondary structure prediction [ 93 ] and tertiary structure prediction as a part of integrative modelling [ 94 ]. Thus, the results of SASA from LASER-Seq or icLASER experiments as well as from computational prediction will be likely integrated in 3D structure modelling in near future, similar to the use of SASA in ab initio protein structure prediction [ 95 ], template-based structure modelling [ 96 ] and native structure discrimination [ 97 ].…”
