dGenomes searched at KEGG Genomes (http://www.genome.jp/kegg/catalog/org_list.html); genome sequences are also available at NCBI (http://www.ncbi.nlm.nih.gov/genomes/MICROBES/microbial_taxtree.html). A complete phosphotransferase system is defined as having a minimum of IIB and IIC domains; some phosphotransferase systems are known to lack a IIA domain but may obtain this function by interacting with a component of an alternative system (Mitchell and Tangney 2005)
