Databases and Web Tools

Bacterial (Huge metagenomics database, great mapping tools) (prokaryote operons) (Toxin-antitoxin pairs)

RNA (tRNA genes) (organism specific tRNA gene database) (codon usage and counting tools)   (Pseudomonas genome database) (TB genes, all) (TB genes, drug resistance) (bacterial cytochrome p450s)

Biochemistry: (the quintessential RNA modification databse) (RNA modification database, monooligo calculator is an excellent supplement for oligo mass spectrometry) (chemical structural database, great for finding vendors too!) (mass spectra database, good for MSn studies of small molecules) (Purine metabolism interactive database)

Omics: (the best one-stop shop for integrative pathway analysis) (proteomics, protein function - consists of Swissprot, which is curated and TremBL which isn't) (more of a pipeline than a database, used to look at gene enrichments) (functional gene annotations) (NCBI gene database -- great 1° pass resource) (repository for microarray and RNAseq data - deposition required for submission of RNAseq data) (proteomics data archive — current MCP submission requirement) (easy-to-use gene ontology resource database)   (multiple sequence alignment program)

Oligos and Molecular Biology: (great tool for molecular cloning) (analyze restriction map of sequence) (has a webchat system that you can enquire technicalities with their specialist before ordering, especially for long oligos or oligos with modifications etc) (good for drawing constructs, free version for mac and windows)
