bovis. For example, M. tuberculosis only found one of the pst -operons to be upregulated. tuberculosis contains three different copies of pstS, two copies each of pstC and pstA, and one copy of pstB, plus a homologous gene, phoT, which has been shown to fulfill the same function as pstB in M. leprae, this is due to duplication of the pst genes. Mycobacteria appear unique in that they contain several copies of high-affinity systems specific for phosphate: In the pathogenic species, such as M. bovis and M.

Phosphorus Transport - Pepperdine Biochemistry Wiki

There are two primary mechanisms for prokaryotic transport of. “phosphate transport in prokaryotes: molecules, mediators, and mechanisms”.

This chelation involves the formation of coordinate bonds between a metal cation and one of the organic derivatives of phosphorus which allows the transport of the phosphorus itself to be net-neutral in its effect of the cell's internal pH (this is excluding the affect of the symport of H+ with phosphorus). The functionality of Pit has been found to be dependent upon the presence of divalent metal cations in the external environment such as Ca2+, Mg2+, Co2+, or Mn2+. Thus, inorganic phosphorus is transported through the Pit primarily in the form of neutral soluble metal chelates (MeHPO 4) ).
