RBS_C125-TupA_rrnBT1
Encoded by the gene tupA from the facultative alkaliphilic strain Bacillus lentus C-125, TupA is a cytoplasmic protein consisting of 489 amino acid residues with a molecular mass of 57.3kDa. TupA homologues are distributed widely among strains of alkaliphilic Bacillus possessing TUP. The function of the TupA protein is not clear, although it was demonstrated that TupA is involved in TUP synthesis. One of the biological functions of TUP, is its involvement in maintaining pH homeostasis at a high pH conditions, under which there is a low level of the antiporter activity. In the cell walls of C-125, a high density of fixed anion charges is generated by dissociation of carboxyl groups of the predominant acidic polymer(the PGlu moiety of TUP), function as an obstacle repulsing hydroxyl ions abundant in the milieu and as a reservoir capturing hydrogen ions generated intracellularly by aerobic respiration.
