http://cdb.ics.uci.edu

A database of general chemical information. The datasets are comprised of various available chemical datasets annotated with interesting properties to train and test machine-learning prediction and searching methods. Tools provided include ChemicalSearch, Virtual Chemical Space, Reaction Explorer, Datasets, and supplemental material. ChemicalSearch is a tool that allows users to find a chemical by basic criteria like molecular weight and predicted logP, or by the more abstract notion of structural similarity. Virtual Chemical Space is a tool which lets users interactively deconstruct target compounds into component precursors and reconstruct similar building-blocks into combinatorial libraries representing the virtual chemical space near the target compound. Reaction Explorer is a synthesis explorer and mechanism explorer. It provides an interactive system for learning and practicing reactions, syntheses and mechanisms in organic chemistry, with advanced support for the automatic generation of random problems, curved-arrow mechanism diagrams, and inquiry-based learning.

ChickVD hosts high-quality sequence variation data, variation analysis in the context of chicken genes, cDNAs, chicken orthologs of human disease genes, genetic markers, quantitative trait loci (QTLs) etc . All data are uniquely mapped onto the RJF draft genome and graphically represented in MapView, an efficient visualization tool that allows users to browse sequence variations in the genomic and functional context. The sub-viewer TraceView assists users to view the vivid graphics of the original traces around the detected SNP. Users may query the data by the online search tool and define concrete limitations to extract records that are best suited to their research needs. For the convenience of data presentation in ChickVD, different types of sequence variations (substitutions, insertions or deletions) are all referred as ???SNPs''. ChickVD is updated constantly as more data generated and is under the continued improvement for its content and functionality

http://cleanest.kobic.re.kr/

A database to provide cleansed EST sequences of classified dbEST libraries. All dbEST libraries were classified according to organism, sequencing center, and eVOC ontologies (for human libraries). For each dbEST library, we provide three different EST sequences: raw, pre-cleansed, and user-cleansed. pre-cleansed ESTs are obtained from major contamination databases and cleaned of contaminated sequences. User-cleansed ESTs, however, involve the use of an automatic user-cleansing pipeline, in which sequences in a user-selected library are cleansed on-the-fly according to user-input options. CleanEST contains 62,008,259 EST sequences (24,000 libraries) with contamination information.

CE is a databases of alignments for all polypeptide chains. A representative set of proteins is available and kept current with the PDB, a method for calculating pairwise structure alignments. CE aligns two polypeptide chains using characteristics of their local geometry as defined by vectors between C alpha positions. Matches are termed aligned fragment pairs (AFPs). Heuristics are used in defining a set of optimal paths joining AFPs with gaps as needed. The path with the best RMSD is subject to dynamic programming to achieve an optimal alignment. For specific families of proteins additional characteristics are used to weight the alignment. Complete details are described in the paper (PDF format).

dbPTM is a database that compiles information on protein post-translational modifications (PTM) such as the modified sites, solvent accessibility of surrounding amino acids, protein secondary and tertiary structures, protein domains, and protein variations. The version 2.0 of dbPTM integrates the experimentally validated PTM sites with referable literatures from Swiss-Prot, Phospho.ELM, O-GLYCBASE, and UbiProt. In all of the collected PTM information, about 25 types of PTM with enough experimentally validated sites are trained the profile hidden Markov models (HMMs) to detect the potential PTM sites with 100% specificity against Swiss-Prot proteins. To help users investigating more detail in each type of PTM, the substrate peptide specificity such as positional amino acid frequency, solvent accessibility and secondary structure surrounding the modified sites are also provided. Moreover, the information of orthologous protein clusters is provided to users for analyzing whether the PTM sites located in the evolutionary conserved regions or not., THIS RESOURCE IS NO LONGER IN SERVICE.

GeneFarm is a database of structural and functional annotation of plant gene and protein families. The goal of the GeneFarm project is to obtain homogeneous, reliable, documented and traceable annotations for plant nuclear genes and gene products and to enter them into added-value database. The improved annotation will allow better data mining of the plant genomes (mainly Arabidopsis thaliana), and more secure planning and design of experiments. It is also a necessary step for building knowledge management tools for integrating plant genomic data, either for plant breeding or to get a broader interactive view of plant biological processes, like gene interaction networks. This re-annotation project, launched is mainly focused on gene families. A complete annotation pipeline using the most efficient prediction tools has been defined. The involved partners, each contributing with genes from his/her field of expertise, have exhaustively annotated families of homologous genes. A database named GeneFarm (Gene Families for Arabidopsis Management) gathers all these expert-curated annotations of plant gene families. Furthermore, collaboration with the Swiss Institute of Bioinformatics is underway to integrate the GeneFarm data into the protein knowledgebase Swiss-Prot.

Genomic Distribution of structural Superfamilies identifies and classifies evolutionary related proteins at the superfamily level in whole genome databases. GenDiS has been curated in direct correspondence with SCOP and represents 4001 highly resolved domains in 1194 structural superfamilies across protein sequence databases. Sequences showing reliable homology to entries in SCOP and PASS2 databases have been obtained from the non-redundant protein sequence database and aligned. Similar alignments of the superfamily members are provided in the genome level. GenDiS provides a platform for cross genome comparison at the superfamily level. GenDis relates proteins sequence information across all strata of taxonomy. One may navigate through the database to obtain structural homologues across different levels in taxonomic classification. The nomenclature of the various genomes and their hierarchy is in direct correspondence with the taxonomy database maintained at the NCBI. Sequence homologues for the various structural members are obtained from the non-redundant protein sequence database employing sensitive sequence search methods. Multiple approaches such as PSI-BLAST, HMMsearch of the HMMer suite and an interacting motif constrained PHI-BLAST have been employed to identify homologues in the sequence databases.

GeneAnnot provides a revised and improved annotation of Affymetrix probe-sets from HG-U95, HG-U133 and HG-U133 Plus2.0. Probe-sets are related to GeneCards genes, by direct sequence comparison of probes to GenBank, RefSeq and Ensembl mRNA sequences, while assigning sensitivity and specificity scores to each probe-set to gene match. Where such matches are not found, probe-sets are annotated by their relation to GenBank mRNA sequences and UniGene clusters. The results are integrated with the GeneCards, GeneLoc and GeneNote databases. HG-U95, HG-U133, HG-U133

Kinomer is a multilevel HMM library that models these protein kinase groups. It allows accurate identification of protein kinases and classification to the appropriate kinase group. Profile hidden Markov models (HMMs) are statistical descriptions of sequence conservation from multiple sequence alignments, and have been shown to outperform standard pairwise sequence comparison methods, both in terms of sensitivity and specificity. HMMs form the basis of protein family and domain description libraries such as SUPERFAMILY and Pfam.
