CC -!- FUNCTION: Catalyzes the phosphorylation of the beta-carboxyl group of
CC aspartic acid with ATP to yield 4-phospho-L-aspartate, which is
CC involved in the branched biosynthetic pathway leading to the
CC biosynthesis of amino acids threonine, isoleucine and methionine.
CC {ECO:0000256|ARBA:ARBA00003121}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-aspartate + ATP = 4-phospho-L-aspartate + ADP;
CC Xref=Rhea:RHEA:23776, ChEBI:CHEBI:29991, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:57535, ChEBI:CHEBI:456216; EC=2.7.2.4;
CC Evidence={ECO:0000256|ARBA:ARBA00047872,
CC ECO:0000256|RuleBase:RU003448};
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 1/4.
CC {ECO:0000256|ARBA:ARBA00004766, ECO:0000256|RuleBase:RU004249}.
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo
CC pathway; L-homoserine from L-aspartate: step 1/3.
CC {ECO:0000256|ARBA:ARBA00004986, ECO:0000256|RuleBase:RU004249}.
CC -!- PATHWAY: Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine
CC from L-aspartate: step 1/5. {ECO:0000256|ARBA:ARBA00005139,
CC ECO:0000256|RuleBase:RU004249}.
CC -!- SIMILARITY: Belongs to the aspartokinase family.
CC {ECO:0000256|ARBA:ARBA00010122, ECO:0000256|RuleBase:RU003448}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
