A server implementation of the UNRES package ( http://www.unres.pl ) for coarse-grained simulations of protein structures with the physics-based UN- RES model, coined a name UNRES server, is pre- sented. In contrast to most of the protein coarse- grained models, owing to its physics-based origin, the UNRES force field can be used in simulations, including those aimed at protein-structure predic- tion, without ancillary information from structural databases; however, the implementation includes the possibility of using restraints. Local energy mini- mization, canonical molecular dynamics simulations, replica exchange and multiplexed replica exchange molecular dynamics simulations can be run with the current UNRES server; the latter are suitable for protein-structure prediction. The user-supplied input includes protein sequence and, optionally, restraints from secondary-structure prediction or small x-ray scattering data, and simulation type and parameters which are selected or typed in. Oligomeric proteins, as well as those containing D-amino-acid residues and disulfide links can be treated. The output is dis- played graphically (minimized structures, trajecto- ries, final models, analysis of trajectory / ensembles); however, all output files can be downloaded by the user. The UNRES server can be freely accessed at http://unres-server.chem.ug.edu.pl
