RT "Brachybacterium sp. M1HQ-2T, whole genome shotgun sequence.";
RL Submitted (MAY-2018) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Specifically catalyzes the cleavage of the D-lactyl ether
CC substituent of MurNAc 6-phosphate, producing GlcNAc 6-phosphate and D-
CC lactate. {ECO:0000256|HAMAP-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};
CC -!- PATHWAY: Amino-sugar metabolism; N-acetylmuramate degradation.
CC {ECO:0000256|HAMAP-Rule:MF_00068}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00068}.
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 aldehyde
CC intermediate with (E)-stereochemistry, followed by the syn addition of
CC water to give product. {ECO:0000256|HAMAP-Rule:MF_00068}.
CC -!- SIMILARITY: Belongs to the GCKR-like family. MurNAc-6-P etherase
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_00068}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
