PULCHRA in pipeline

PMCID: 5932063
PMID: 29720613
DOI: 10.1038/s41598-018-25329-4

[…] landscapes of the hsp90 proteins in a coarse-grained representation. the coarse-grained conformational ensembles of the hsp90 structures were then subjected to all-atom reconstruction using pulchra method and cg2aa tool that derived atomistic structures from simulation trajectories. the all-atom conformations were additionally optimized using the 3drefine method that utilizes […]

[…] only the lowest mode. remaining four low modes were included as perturbation terms about the lowest mode,, full atom structures except hydrogen atoms of the two conformations were reconstructed on pulchra [], and, heavy-atom rmsds between each of these reconstructed structures and the open state were calculated. out of the reconstructed two structures, the one with the smaller rmsd was chosen […]

[…] cg protein representation, four steps were used according from the protocol described by sansom and coworkers []. firstly, the backbone of the protein was grown from the cg cα particles using the pulchra algorithm []. secondly, the missing side chain atoms of the protein were added using in modeller []. note that the advantage of these two steps is to preserve the original coordinates […]

[…] at lipid fragments with the corresponding cg fragments from an energy-minimized library of atomistic lipid conformations. the protein backbone is reconstructed by the cg backbone trace using pulchra [] and the side chains using modeller [,]. atomistic molecular dynamics (at-md) simulations were performed using the gromos96 53a6 force field that has been widely used in simulation studies […]

[…] and/or all-atom model of the folded protein, based on the knowledge of the positions of the central cα atoms only. both knowledge-based approaches such and maxsprout [] and de novo methods including pulchra [] and remo [] have been developed, to try and resolve the cα- trace problem. in the case of the backbone atoms, the geometric algorithm introduced by purisima and scheraga [], […]

[…] (at) model was done in two steps as previous studies described , . briefly, the representative dap12-nkg2c trimer structure was clustered from cg-md trajectories and converted to an at model by pulchra software initially; secondly, this at model was inserted into a pre-equilibrated atomistic model of lipid bilayer using the inflategro method . the system was subjected to 1000 steps […]
