Database that describes the complete genome sequence of E. coli K-12 MG1655, the nucleotide position and function of every its genes, several types of cellular regulation, and metabolic pathways.
Repository of information about the 3D structures of large biological molecules, including proteins and nucleic acids, and their relationships to sequence, function, and disease.
Retrieves protein information (inluding sequences and annotations) from a variety of sources, including SwissProt, PIR, PRF, PDB, and translations from annotated coding regions in GenBank and RefSeq.
Provides views for genomes, complete chromosomes, sequence maps with contigs, and integrated genetic and physical maps for Archaea, Bacteria, Eukaryotae, Viruses, Viroids
This site contains the reference sequence and working draft assemblies for a large collection of genomes. Gives annotations, expression, homology and other information on groups of genes and maps your sequence to the genome.
General purpose multiple sequence alignment program for DNA or proteins. It produces multiple sequence alignments of divergent sequences and calculates the best match for the selected sequences, and lines them up so that the identities, similarities and differences can be seen.
