CC Evidence={ECO:0000256|HAMAP-Rule:MF_00315};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00315};
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00315};
CC Note=Binds 1 thiamine pyrophosphate per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_00315};
CC -!- PATHWAY: Metabolic intermediate biosynthesis; 1-deoxy-D-xylulose 5-
CC phosphate biosynthesis; 1-deoxy-D-xylulose 5-phosphate from D-
CC glyceraldehyde 3-phosphate and pyruvate: step 1/1.
CC {ECO:0000256|ARBA:ARBA00004980, ECO:0000256|HAMAP-Rule:MF_00315}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_00315}.
CC -!- SIMILARITY: Belongs to the transketolase family. DXPS subfamily.
CC {ECO:0000256|ARBA:ARBA00011081, ECO:0000256|HAMAP-Rule:MF_00315}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
