Where do I start?

Start with a keyword search for the name of a gene or protein.

Start with the nucleotide sequence of your gene or amino acid sequence of your protein and blast against any complete genome. Use one or more query sequences to search one or more genomes.

Start from the annotation status table of the Streptococcus page, which provides quick access to proteins about which much is known (named genes in subsystems), little is known (named genes not in subsystems and hypothetical genes in subsystems), or nothing is known (hypothetical genes not in subsystems).

Start from the subsystems tree to view the phylogenetic distribution of an interesting biological process.

Start from the essential genes page to view essential genes in model organisms and to project essentiality to closely or distantly related organisms.

Start from a virtual structural proteome to investigate proteins about which structural information is available in PDB.
