HOMCOS : Searching and Modeling of 3D Structures of Complexes

[Go to Japanese page] Help page

HOMCOS(HOMology modeling of COmplex Structure) is a server for modeling complex 3D structures using 3D molecular similarities based on template complex 3D structures in PDB. For a given amino acid sequence or a chemical strucvure, the server provides list of contacting molecules in PDB, predicted complex 3D structure based on the template PDB structures. BLAST is employed for the amino acids sequence search, KCOMBU is used for the chemical structure search.

Services Queries Descriptions

Analysis of mutation of 3D clusters with the help of HOMCOS

TOGOTV releases a Japanese tutorial movie for HOMCOS (https://togotv.dbcls.jp/20220618.html) (2022/06/17)


BLAST is employed for the amino acids sequence search, KCOMBU is used for the chemical structure search.

HOMCOS is developed and maintained by Protein Data Bank Japan, IPR, Osaka University. It is now supported by the project "Platform for Drug Discovery, Informatics, and Structural Life Science" by MEXT, Japan.

This server is based on the concept of HOMCOS server developed by NAIST.

A part of the services of the HOMCOS server can be accessed by VaProS server. HOMCOS is called "3D Interaction" in the VaProS server.
