Comments

CATALYTIC ACTIVITY: ATP + L-aspartate = ADP + 4-phospho-L-aspartate.
ENZYME REGULATION: Lysine-sensitive (By similarity).
PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; tetrahydrodipicolinate from L-aspartate: step 1/4 .
PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; L-homoserine from L-aspartate: step 1/3 .
PATHWAY: Amino-acid biosynthesis; L-threonine biosynthesis; L-threonine from L-aspartate: step 1/5 .
SUBUNIT: Tetramer consisting of 2 isoforms Alpha (catalytic) and 2 isoforms Beta (function not known).

ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative initiation.
