<p>This domain is found at the N terminus of tetrahydrodipicolinate N-acetyltransferase (DapH) which catalyses the acylation of L-2-amino-6-oxopimelate to 2-N-acetyl-6-oxopimelate in the meso-diaminopimelate/lysine biosynthetic pathway of bacteria, blue-green algae, and plants [<cite idref="PUB00013971"/>]. The N-terminal domain as defined here contains three alpha-helices and two twisted hairpin loops [<cite idref="PUB00020828"/>]. </p> Tetrahydrodipicolinate acetyltransferase, N-terminal
