Identifier
MURR
Protein name
RecName: Full=HTH-type transcriptional regulator MurR;
AltName: Full=MurPQ operon repressor;
Gene name
murR

Comments [?]

Function Represses the expression of the murPQ operon involved in the uptake and degradation of N-acetylmuramic acid (MurNAc). Binds to two adjacent inverted repeats within the operator region. MurNAc 6-phosphate, the substrate of MurQ, is the specific inducer that weakens binding of MurR to the operator.
Pathway Amino-sugar metabolism; N-acetylmuramate degradation [regulation].
Subunit Homotetramer.
