Cofactor

Binds 1 magnesium ion per subunit By similarity.

Binds 1 thiamine pyrophosphate per subunit By similarity.

Pathway

Metabolic intermediate biosynthesis; 1-deoxy-D-xylulose 5-phosphate biosynthesis; 1-deoxy-D-xylulose 5-phosphate from D-glyceraldehyde 3-phosphate and pyruvate: step 1/1. HAMAP-Rule MF_00315

Subunit structure

Homodimer By similarity.

Sequence similarities

Belongs to the transketolase family. DXPS subfamily.
