Welcome to HIC-Up, the Hetero-compound Information Centre - Uppsala, a freely accessible resource for structural biologists who are dealing dealing with hetero-compounds ("small molecules").
This service is provided and maintained by Gerard Kleywegt at the Department of Cell and Molecular Biology, Uppsala University.
This site contains information about hetero-compounds encountered in files from the Protein Data Bank (PDB). It is updated once or twice a year.
If you use information from this site in your publications, please cite one of the following papers:
For every compound, a subset of the following information is available:
There are various ways in which you try to locate a particular compound:
The first release of HIC-Up was in September, 1997. Prior to that, a repository with X-PLOR topology and parameter entries (automatically generated with XPLO2D) was maintained in Uppsala, with a mirror at Yale, and a separate repository with O-related information existed as well.
The number of entries in HIC-Up has developed as follows:
