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}.
