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 lysine, threonine, isoleucine and
CC methionine. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-aspartate = 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 -!- ACTIVITY REGULATION: Feedback inhibition by lysine and threonine.
CC {ECO:0000250}.
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 1/4.
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo
CC pathway; L-homoserine from L-aspartate: step 1/3.
CC -!- PATHWAY: Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine
CC from L-aspartate: step 1/5.
CC -!- SUBUNIT: Heterotetramer consisting of 2 isoforms Alpha (catalytic and
CC regulation) and of a homodimer of 2 isoforms Beta (regulation).
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative initiation; Named isoforms=2;
CC Name=Alpha; Synonyms=Aspartokinase subunit alpha;
CC IsoId=P0A4Z9-1; Sequence=Displayed;
CC Name=Beta; Synonyms=Aspartokinase subunit beta;
CC IsoId=P0A4Z9-2; Sequence=VSP_018661;
CC -!- SIMILARITY: Belongs to the aspartokinase family. {ECO:0000305}.
