AAindex Database of amino acid indices, amino acid mutation matrices, and pair-wise contact potentials
AAindex Amino Acid index database
Amino Acids Sequence Database (PRF/SEQDB) This database consists of amino acid sequences of peptides and proteins, including sequences predicted from genes. You can also search literature in which the sequence is presented.Sequences not included in EMBL, GenBank and SwissProt are also found in PRF/SEQDB since it is constructed on the basis of all amino acid sequences of peptides and proteins reported in literature.



metalife bioinformatics database metalife makes available various bioinformatics algorithms, which perform all essential tasks in sequence analysis and sequence-based predictions.



ChEMBL Manually curated database of bioactive molecules with drug-like properties. It brings together chemical, bioactivity, and genomic data to aid the translation of genomic information into effective new drugs.  



SABIO-RK: database for biochemical reactions and their kinetic properties Database for biochemical reactions and their kinetic properties




SWEET-DB SWEET-DB offers access to CarbBank entries via graphics-oriented surface. Bibliographic search and similarity-based structure search is possible. 3D structures (optimized by TINKER) of hit entries are displayed and can be saved as PDB files.
Carbohydrate-Active Enzymes This server describes the families of structurally-related catalytic and carbohydrate-binding modules (or functional domains) of enzymes that degrade, modify, or create glycosidic bonds.

Current chemical reactions Contains single- and multi-step new synthetic methods. The overall reaction flow is provided for each method, along with a detailed and accurate graphical representation of each reaction step.
ProQuest materials science collection This databases provides access to Materials Research Database with METADEX, ProQuest Materials Science Journals, and deep indexing of over a million tables and figures.
Reaxys Reaxys is a web-based search and retrieval system for chemical compounds, bibliographic data and chemical reactions.
SciFinder SciFinder provides access to several Chemical Abstracts Service databases, including Chemical Abstracts, Registry, CASREACT, CHEMLIST, and CHEMCAT..



ADME DB ADME DB is a database containing information on Human Cytochrome P450 metabolism, kinetics, transporter and structure. The information is organized by category (therapeutic area), drug name, enzyme, reaction, and type. The database includes about 11 000 entries, 5000 reactions, 3000 references and 6500 structures in mol format.
BioFrontier / P450 BioFrontier/P450 is a system, which enables every user to search for information about Human Cytochrome P450. It uses a structure formula or reaction formula as a search query. In addition to the searching function, the system can also predict information about unknown metabolites by analyzing data in the system.




BRENDA-The Comprehensive Enzyme Information System BRENDA is the main collection of enzyme functional data available to the scientific community. The enzymes are classified according to the Enzyme Commission list of enzymes. Some 3500 “different” enzymes are covered.
Carbohydrate-Active Enzymes This server describes the families of structurally-related catalytic and carbohydrate-binding modules (or functional domains) of enzymes that degrade, modify, or create glycosidic bonds.
Enzymes and Metabolic Pathways The EMP Project, Inc. was incorporated in 1999 to provide organizational, legal, and financial support for the EMP group projects, such as Enzymes and Metabolic Pathways Database (EMP) and Metabolic Pathways Database (MPW). EMP/MPW is the most comprehensive single source of computerized biochemical data available today. Moreover, this is a powerful tool for metabolic reconstruction and modeling, unmatched in either academia or the genomics industry. Both databases are currently used in a number of public and commercial genomics projects.
