Enzyme Information

2.7.2.4
Aspartate kinase.
based on mapping to UniProt P08660
ATP + L-aspartate = ADP + 4-phospho-L-aspartate.
-!- The enzyme from Escherichia coli is a multifunctional protein, which also catalyzes the reaction of EC 1.1.1.3. -!- This is also the case for two of the four isoenzymes in Arabidopsis thaliana. -!- The equilibrium constant strongly favors the reaction from right to left, i.e. the non-physiological direction of reaction.
