The RESID Database of protein structure modifications and the NRL-3D Sequence-Structure Database

The RESID Database is a comprehensive collection of annotations and structu res for protein post-translational modifications including N-terminal, C-te rminal and peptide chain cross-link modifications. The RESID Database inclu des systematic and frequently observed alternate names, Chemical Abstracts Service registry numbers, atomic formula and weights, enzyme activities, ta xonomic range, keywords, literature citations with database crossreferences , structural diagrams and molecular models. The NRL-3D Sequence-Structure D atabase is derived from the three-dimensional structure of proteins deposit ed with the Research Collaboratory for Structural Bioinformatics Protein Da ta Bank. The NRL-3D Database includes standardized and frequently observed alternate names, sources, keywords, literature citations, experimental cond itions and searchable sequences from model coordinates, These databases are freely accessible through the National Cancer Institute-Frederick Advanced Biomedical Computing Center at these web sites: http://www.ncifcrf.gov/RES ID, http://www.ncifcrf.gov/ NRL-3D; or at these National Biomedical Researc h Foundation Protein Information Resource web sites: http://pir.georgetown. edu/pirwww/dbinfo/resid.html,http://pir.georgetown.edu/pirwww/dbinfo/nrl3d. html.
