LITERATURE

PdxR
PdxR is a direct activator of the pdxST operon, has a regulatory function in de novo synthesis of pyridoxal 5'-phosphate, encoded by gene pdxR, PdxR is a member of the MocR/GabR subfamily with an N-terminal putative DNA-binding domain and a C-terminal aminotransferase-like domain. PdxR is also a negative autoregulator, and its ability to repress is increased by pyridoxal 5'-phosphate. PdxR-like proteins, for which PLP plays just a signalling role, form a separate functional group among the MocR/GabRtype proteins. Mutational analysis of the PdxR binding site, overview
