2,3,4,5-tetrahydropyridine-2,6-dicarboxylate N-succinyltransferase catalyzes the conversion of the cyclic tetrahydrodipicolinate (THDP) into the acyclic N-succinyl-L-2-amino-6-oxopimelate using succinyl-CoA
2,3,4,5-tetrahydropyridine-2,6-dicarboxylate N-succinyltransferase; 2,3,4,5-tetrahydropyridine-2,6-dicarboxylate N-succinyltransferase (DapD) is involved in the succinylated branch of the "lysine biosynthesis via diaminopimelate (DAP)" pathway (GenProp0125). This model represents a clade of DapD sequences most closely related to the actinobacterial DapD family represented by the TIGR03535 model. All of the genes evaluated for the seed of this model are found in genomes where the downstream desuccinylase is present, but known DapD genes are absent. Additionally, many of the genes identified by this model are found proximal to genes involved in this lysine biosynthesis pathway.

Putative 2,3,4,5-tetrahydropyridine-2,6-dicarboxylate (THDP) N-succinyltransferase (THP succinyltransferase), C-terminal left-handed parallel alpha-helix (LbH) domain: This group is composed of mostly uncharacterized proteins containing an N-terminal domain of unknown function and a C-terminal LbH domain with similarity to THP succinyltransferase LbH. THP succinyltransferase catalyzes the conversion of tetrahydrodipicolinate and succinyl-CoA to N-succinyltetrahydrodipicolinate and CoA. It is the committed step in the succinylase pathway by which bacteria synthesize L-lysine and meso-diaminopimelate, a component of peptidoglycan. The enzyme is trimeric and displays the left-handed parallel alpha-helix (LbH) structural motif encoded by the hexapeptide repeat motif.

Left-handed parallel beta-Helix (LbetaH or LbH) domain: The alignment contains 5 turns, each containing three imperfect tandem repeats of a hexapeptide repeat motif (X-[STAV]-X-[LIV]-[GAED]-X). Proteins containing hexapeptide repeats are often enzymes showing acyltransferase activity, however, some subfamilies in this hierarchy also show activities related to ion transport or translation initiation. Many are trimeric in their active forms.

Serine acetyltransferase (SAT): SAT catalyzes the CoA-dependent acetylation of the side chain hydroxyl group of L-serine to form O-acetylserine, as the first step of a two-step biosynthetic pathway in bacteria and plants leading to the formation of L-cysteine. This reaction represents a key metabolic point of regulation for the cysteine biosynthetic pathway due to its feedback inhibition by cysteine. The enzyme is a 175 kDa homohexamer, composed of a dimer of homotrimers. Each subunit contains an N-terminal alpha helical region and a C-terminal left-handed beta-helix (LbH) subdomain with 5 turns, each containing a hexapeptide repeat motif characteristic of the acyltransferase superfamily of enzymes. The trimer interface mainly involves the C-terminal LbH subdomain while the dimer (of trimers) interface is mediated by the N-terminal alpha helical subdomain.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
