CC -!- FUNCTION: Catalyzes the gamma-elimination of phosphate from L-
CC phosphohomoserine and the beta-addition of water to produce L-
CC threonine. {ECO:0000256|ARBA:ARBA00003648,
CC ECO:0000256|PIRNR:PIRNR038945}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-homoserine = L-threonine + phosphate;
CC Xref=Rhea:RHEA:10840, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:57590, ChEBI:CHEBI:57926; EC=4.2.3.1;
CC Evidence={ECO:0000256|ARBA:ARBA00000051,
CC ECO:0000256|PIRNR:PIRNR038945};
CC -!- COFACTOR:

CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|PIRNR:PIRNR038945, ECO:0000256|PIRSR:PIRSR038945-1};
CC -!- PATHWAY: Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine
CC from L-aspartate: step 5/5. {ECO:0000256|ARBA:ARBA00004979,
CC ECO:0000256|PIRNR:PIRNR038945}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738}.
CC -!- SIMILARITY: Belongs to the threonine synthase family.
