N-terminal NAD(P)-binding domain of dihydrodipicolinate reductase (DHDPR) and similar proteins; ...
86-174 4.03e-03

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 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.
