CC ChEBI:CHEBI:57476, ChEBI:CHEBI:57590, ChEBI:CHEBI:456216;
CC EC=2.7.1.39; Evidence={ECO:0000256|ARBA:ARBA00000528,
CC ECO:0000256|HAMAP-Rule:MF_00384};
CC -!- PATHWAY: Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine
CC from L-aspartate: step 4/5. {ECO:0000256|ARBA:ARBA00005015,
CC ECO:0000256|HAMAP-Rule:MF_00384}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00384}.
CC -!- SIMILARITY: Belongs to the GHMP kinase family. Homoserine kinase
CC subfamily. {ECO:0000256|ARBA:ARBA00007370, ECO:0000256|HAMAP-
CC Rule:MF_00384}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
