A 20-kDa Brevibacterium lactofermentum protein was detected when purifying the His-tagged FtsZBL. The protein was identified by matrix-assisted laser desorption/ionisation time of flight as the inorganic pyrophosphatase encoded by the ppa gene, which is present as a single copy in the genome of Corynebacterium glutamicum. The ppa gene was cloned from B. lactofermentum chromosomal DNA by polymerase chain reaction; it seemed to be an essential gene and it might represent an attractive target for drug discovery. The cloned ppa gene complemented a ppa- Escherichia coli mutant and a ppa-gfp gene fusion revealed that the gene product mainly accumulated at the cell poles in both E. coli and B. lactofermentum.
