Dihydrodipicolinate reductase, C-terminus; Dihydrodipicolinate reductase (DapB) reduces the alpha,beta-unsaturated cyclic imine, dihydro-dipicolinate. This reaction is the second committed step in the biosynthesis of L-lysine and its precursor meso-diaminopimelate, which are critical for both protein and cell wall biosynthesis. The C-terminal domain of DapB has been proposed to be the substrate- binding domain.

N-terminal NAD(P)-binding domain of dihydrodipicolinate reductase (DHDPR) and similar proteins; DHDPR (EC 1.17.1.8), also called 4-hydroxy-tetrahydrodipicolinate reductase, or HTPA reductase, is a product of an essential gene referred to as dapB. It catalyzes the NAD(P)H-dependent reduction of 2,3-dihydrodipicolinate (DHDP) to 2,3,4,5-tetrahydrodipicolinate (THDP). DHDPR could also function as a dehydratase in addition to the role of a nucleotide dependent reductase. DHDPR is a component of the biosynthetic pathway that generates meso-diaminopimelate, a component of bacterial cell walls, and the amino acid L-lysine in various bacteria, archaea, cyanobacteria and higher plants. The enzyme is a homotetramer where each monomer is composed of two domains, an N-terminal NAD(P)-binding domain which forms a Rossmann fold, and a C-terminal substrate-binding domain that forms an open, mixed alpha-beta sandwich.

N-terminal NAD(P)-binding domain of native NAD(P)H-dependent amine dehydrogenases (nat-AmDHs) and similar proteins; The family corresponds to a group of native NAD(P)H-dependent amine dehydrogenases (nat-AmDHs) that catalyze the reductive amination of ketone and aldehyde substrates using NAD(P)H as the hydride source. nat-AmDHs can naturally catalyze the amination of 'neutral' carbonyl compounds using ammonia. They possess tremendous potential for the efficient asymmetric synthesis of alpha-chiral amines. The family also contains 2,4-diaminopentanoate dehydrogenase (DAPDH) and similar proteins. DAPDH, also known as ORD, is involved in the ornithine fermentation pathway. It catalyzes the oxidative deamination of (2R,4S)-2,4-diaminopentanoate ((2R,4S)-DAP) to yield 2-amino-4-ketopentanoate (AKP). Although DAPDH is more efficient with (2R,4S)-DAP, the diastereoisomer (2R,4R)-DAP can also be metabolized. Different forms of DAPDH exist which utilize NAD(+) (EC 1.4.1.26) or NAD(+)/NADP(+) (EC 1.4.1.12). Members of this family contain an N-terminal Rossmann fold NAD(P)-binding domain and a C-terminal dimerization domain.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(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
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
