We describe a revised and updated version of the program package SMMP (Simple Molecular Mechanics for Proteins) [F. Eisenmenger, U.H.E. Hansmann, Sh. Hayryan, C.-K. Hu, Comput. Phys. Comm. 138 (2001) 192-212]. SMMP is an open-source FORTRAN package for molecular simulation of proteins within the standard geometry model. It is designed as a simple and inexpensive tool for researchers and students to become familiar with protein simulation techniques. This announcement describes the first major revision of this software package and its newly added features.

Eisenmenger, U.H.E. Hansmann, Sh. Hayryan, C.-K. Hu, Comput. Phys. Comm. 138 (2001) 192-212 Does the new version supersede the previous version?:Yes Nature of physical problem:Molecular mechanics computations and Monte Carlo simulation of proteins Reasons for the new version:Increased functionality Summary of revisions:Changes in energy function and protein representation; differences in program structure and organization; new functionalities added; miscellaneous changes and additions Method of solution:Utilizes ECEPP2/3 and FLEX potentials. Includes Monte Carlo simulation algorithms for canonical, as well as for generalized ensembles Restrictions on the complexity of the problem:The consumed CPU time increases with the size of protein molecule Typical running time:Depends on the size of the molecule under simulation Unusual features of the program:No © 2005 Elsevier B.V.
