PhpR, as a unique transcriptional regulator, represses the expression of pyridoxal 5′-phosphate-binding protein YggS in Alcaligenes
ABSTRACT YggS (COG0325 family) was widely conserved across the three domains of life and had been implicated in pyridoxal 5′-phosphate (PLP) homeostasis. However, transcriptional regulators that directly controlled yggS had remained unknown. Here, using Alcaligenes faecalis JQ135, PhpR, a previously unrecognized MocR-f...
