Abstract

Treponema pallidum and Treponema denticola encode within their genomes homologues of energy coupling and regulatory proteins of the phosphoenolpyruvate: sugar phosphotransferase system (PTS) but no recognizable homologues of PTS permeases. The first biochemical description of PTS phosphoryl-transfer chains in an organism that lacks PTS permeases is described.

Abstract

The purification and biochemical characterization of four predicted glutaminases from Escherichia coli (YbaS and YneH) and Bacillus subtilis (YlaM and YbgJ) is described. The results provide insight into crystal structures of YbaS and YbgJ in free state as well as the structure of the covalent complex of YbgJ with the glutaminase inhibitor 6-diazo-5-oxo-L-nor-leucine and also involvement of YneH in the assimilation of glutamine and the contribution of YneH and YbaS in acid resistance.
