MODELLER is most frequently used for homology or comparative modeling
of protein three-dimensional structure: the user provides an alignment
of a sequence to be modeled with known related structures and MODELLER
will automatically calculate a full-atom model. More generally, MODELLER
models protein 3D structure by satisfaction of spatial restraints
(A. Sali & T.L. Blundell. J.Mol.Biol. 234, 779-815, 1993). In principle,
the restraints can be derived from a number of different sources. These
include homologous structures (comparative modeling), NMR experiments
(NMR refinement), rules of secondary structure packing (combinatorial
modeling), cross-linking experiments, fluorescence spectroscopy, image
reconstruction in electron microscopy, site-directed mutagenesis,
intuition, residue-residue and atom-atom potentials of mean force, etc.
The output of MODELLER is a 3D structure of a protein that satisfies
these restraints as well as possible. The optimization is carried out
by the variable target function procedure employing methods of conjugate
gradients and molecular dynamics with simulated annealing. The program
includes a 100-page manual. MODELLER is written in Fortran and is meant
to run on a UNIX system.
MODELLER is available free of charge to non-profit institutions.
