Function
function
Bifunctional aspartate kinase and homoserine dehydrogenase that catalyzes the first and the third steps toward the synthesis of lysine, methionine and threonine from aspartate.
Catalytic activity
- ATP + L-aspartate = 4-phospho-L-aspartate + ADPThis reaction proceeds in the forward direction.
Cofactor
Pathway
