The alkaliphilic bacterium ${it Bacillus alcalophilus}$ AV1934, isolated from human feces, recent has indicated novel potassium ion coupling to motility in this extremophile. We report draft sequences that will facilitate an examination of whether that coupling is part of a larger cycle of potassium ion-coupled transporters. This draft genome has 4,095 predicted genes and 4,063 predicted proteins. The whole-genome shotgun project has been deposited in Genbank under the accession no. ALPT02000000. In addition to the ${it mot}$ genes encoding the MotPS channel that uses either potassium or sodium coupling, two loci encoding multisubunit Mrp-type antiporters, were found. The ${it B. alcalophilus}$ AV1934 genome reveals no tripartite ATP-independent (TRAP-T family) uptake systems, a major sodium-coupled complement in the other two alkaliphiles. The ${it B. alcalophilus}$ AV1934 genomic data will enable us to test the hypothesis of a major role of potassium in ion coupling in this extremophile.
