Type	Tit le	Reference
adaptation	0001 AGAB	See below
Nature of problem: Determination of the spatial conformation of a protein from its amino acid sequence.
Solution method: Optimization, under an energy criterion, by rotation around the bonds C alpha-C', C'-N, N-C alpha' and C alpha-C beta.
Restrictions: Only proteins involving the amino acids ala, arg, asn, asp, cys, glu, gln, gly, his, ile, leu, met, phe, pro, ser, thr, trp, tyr, and val may be studied. The amino acid sequence of the protein must be known.
Unusual features: The graphic representation of the protein may be obtained from the Cartesian coordinates of its atoms, produced by this program. The plotting subroutines, available at the institution where the program will be run, may be used for this purpose.
Running time: Dependent on the size of the protein and the level of optimization. used.

Journal reference: Comput. Phys. Commun. 41(1986)169

Classification: 3, 16.1.
Nature of problem: Determination of the optimal spatial conformations and relative positions of two proteins from their amino acid sequence.
Solution method: Optimization, under an energy criterion, by rotation around the bonds C alpha-C', C'-N, N-C alpha' and C alpha-C beta (see Fig 1).
Restrictions: Only proteins involving the amino acids ala, arg, asn, asp, cys, glu, gln, gly, his, ile, leu, met, phe, pro, ser, thr, trp, tyr, and val may be studied. The amino acid sequence of the protein must be known.
Unusual features: The graphic representation of the protein may be obtained from the Cartesian coordinates of its atoms, produced by this program. The plotting subroutines, available at the institution where the program will be run, may be used for this purpose.
Running time: Dependent on the size of the protein and the level of optimization used.
