OX NCBI_TaxID=1454202 {ECO:0000313|EMBL:CEO41756.1, ECO:0000313|Proteomes:UP000019762}; RN [1] {ECO:0000313|EMBL:CEO41756.1, ECO:0000313|Proteomes:UP000019762} RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=ANT220 {ECO:0000313|Proteomes:UP000019762}; RA Genoscope - CEA; RL Submitted (DEC-2014) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Specifically catalyzes the cleavage of the D-lactyl CC ether substituent of MurNAc 6-phosphate, producing GlcNAc 6- CC phosphate and D-lactate. Together with AnmK, is also required for CC the utilization of anhydro-N-acetylmuramic acid (anhMurNAc) either CC imported from the medium or derived from its own cell wall murein, CC and thus plays a role in cell wall recycling. {ECO:0000256|HAMAP- CC Rule:MF_00068}. CC -!- CATALYTIC ACTIVITY: CC Reaction=H2O + N-acetyl-D-muramate 6-phosphate = (R)-lactate + N- CC acetyl-D-glucosamine 6-phosphate; Xref=Rhea:RHEA:26410, CC ChEBI:CHEBI:15377, ChEBI:CHEBI:16004, ChEBI:CHEBI:57513, CC ChEBI:CHEBI:58722; EC=4.2.1.126; Evidence={ECO:0000256|HAMAP- CC Rule:MF_00068, ECO:0000256|SAAS:SAAS01114880}; CC -!- PATHWAY: Amino-sugar metabolism; 1,6-anhydro-N-acetylmuramate CC degradation. {ECO:0000256|HAMAP-Rule:MF_00068}. CC -!- PATHWAY: Amino-sugar metabolism; N-acetylmuramate degradation. CC {ECO:0000256|HAMAP-Rule:MF_00068, ECO:0000256|SAAS:SAAS00767189}. CC -!- PATHWAY: Cell wall biogenesis; peptidoglycan recycling. CC {ECO:0000256|HAMAP-Rule:MF_00068}. CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00068, CC ECO:0000256|SAAS:SAAS00767192}. CC -!- MISCELLANEOUS: A lyase-type mechanism (elimination/hydration) is CC suggested for the cleavage of the lactyl ether bond of MurNAc 6- CC phosphate, with the formation of an alpha,beta-unsaturated CC aldehyde intermediate with (E)-stereochemistry, followed by the CC syn addition of water to give product. {ECO:0000256|HAMAP- CC Rule:MF_00068}. CC -!- SIMILARITY: Belongs to the GCKR-like family. MurNAc-6-P etherase CC subfamily. {ECO:0000256|HAMAP-Rule:MF_00068, CC ECO:0000256|SAAS:SAAS00767176}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:CEO41756.1}.
