CC -!- FUNCTION: Catalyzes the acyloin condensation reaction between C atoms 2
CC and 3 of pyruvate and glyceraldehyde 3-phosphate to yield 1-deoxy-D-
CC xylulose-5-phosphate (DXP). Is a limiting enzyme for plastidic
CC isoprenoid biosynthesis and essential for chloroplast development.

CC ECO:0000269|PubMed:8653115}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glyceraldehyde 3-phosphate + H(+) + pyruvate = 1-deoxy-D-
CC xylulose 5-phosphate + CO2; Xref=Rhea:RHEA:12605, ChEBI:CHEBI:15361,

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:12606;
CC Evidence={ECO:0000269|PubMed:10982425};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250};
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000250};
CC Note=Binds 1 thiamine pyrophosphate per subunit. {ECO:0000250};
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:0000269|PubMed:10982425, ECO:0000269|PubMed:11264287}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- INTERACTION:
CC Q38854; Q9SDN0: ATJ20; NbExp=4; IntAct=EBI-4476357, EBI-6897500;
CC Q38854; Q38854: DXS; NbExp=5; IntAct=EBI-4476357, EBI-4476357;
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma
CC {ECO:0000305|PubMed:18236010}.
CC -!- TISSUE SPECIFICITY: Widely expressed. {ECO:0000269|PubMed:10982425}.
CC -!- INDUCTION: Circadian-regulated with a peak in the late period of dark
CC phase and early period of the light phase.
CC {ECO:0000269|PubMed:15863698}.
CC -!- DISRUPTION PHENOTYPE: Albino phenotype and seedling lethal when
CC homozygous. The phenotype is caused by an early arrest in chloroplast
CC differentiation. {ECO:0000269|PubMed:10982425,
CC ECO:0000269|PubMed:12447549, ECO:0000269|PubMed:8653115}.
CC -!- MISCELLANEOUS: Plants over-expressing CLA1 show increased levels of
CC plastid isoprenoids derived from the methylerythritol 4-phosphate (MEP)
CC pathway, such as chlorophylls, tocopherols, carotenoids, abscisic acid,
CC and gibberellin (PubMed:11264287). Mutant plants treated with exogenous
CC mevalonic acid partially recover chlorophyll accumulation and plastid
CC development (PubMed:12447549). {ECO:0000305|PubMed:11264287,
CC ECO:0000305|PubMed:12447549}.
CC -!- SIMILARITY: Belongs to the transketolase family. DXPS subfamily.
CC {ECO:0000305}.
