CC   -!- FUNCTION: Represses the expression of the murPQ operon involved in the
CC       uptake and degradation of N-acetylmuramic acid (MurNAc). Binds to two
CC       adjacent inverted repeats within the operator region. MurNAc 6-
CC       phosphate, the substrate of MurQ, is the specific inducer that weakens
CC       binding of MurR to the operator. {ECO:0000255|HAMAP-Rule:MF_02108}.
CC   -!- PATHWAY: Amino-sugar metabolism; N-acetylmuramate degradation
CC       [regulation].
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_02108}.
