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.
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.
