Diaminopimelic acid

( (R*,s*)-2,6-diamino-heptanedioic acid

C7H14N2O4 (190.0954)


Diaminopimelic acid or DAPA is a lysine-like amino acid derivative that is a key component of the bacterial cell wall. DAPA is incorporated or integrated into peptidoglycan of gram negative bacteria and is the attachment point for Brauns lipoprotein (BLP or Murein Lipoprotein). BLP is found in gram-negative cell walls and is one of the most abundant membrane proteins. BLP is bound at its C-terminal end (a lysine) by a covalent bond to the peptidoglycan layer (specifically to diaminopimelic acid molecules) and is embedded in the outer membrane by its hydrophobic head (a cysteine with lipids attached). BLP tightly links the two layers and provides structural integrity to the bacterial outer membrane. Diaminopimelic acid can be found in human urine or feces due to the lysis or enzymatic breakdown of gram negative gut microbes. Acquisition and generation of the data is financially supported in part by CREST/JST. 2,6-Diaminoheptanedioic acid is an endogenous metabolite.

   

Tetrahydrodipicolinate

(2S)-2,3,4,5-Tetrahydro-2,6-pyridinedicarboxylic acid

C7H9NO4 (171.0532)


Tetrahydrodipicolinate (CAS: 2353-17-5), converted from L-aspartate, is an important intermediate in the lysine biosynthesis pathway. Several pathways are now recognized in bacteria, most algae, fungi, and higher plants for the biosynthesis of lysine. They are divided into two groups: (1) the diaminopimelate (DAP) pathways, and (2) the alpha-aminoadipate (AAA) pathways. In the pathways that belong to the DAP group, lysine is produced from aspartate (along with methionine, threonine, and isoleucine). All of these pathways share the upper segments, which include the four steps required for the conversion of L-aspartate into tetrahydrodipicolinate. They also share the last step, which is the conversion of the intermediate meso-diaminopimelate (D,L-DAP, or meso-DAP) into lysine. However, these pathways differ in the routes leading from tetrahydrodipicolinate to meso-diaminopimelate. The four variations include: (I) the succinylase variant, which involves succinylated intermediates, where tetrahydrodipicolinate is converted into meso-diaminopimelate in four enzymatic steps; (II) the acetylase variant, which involves acetylated intermediates, where tetrahydrodipicolinate is converted into meso-diaminopimelate in four enzymatic steps; (III) the dehydrogenase variant, in which tetrahydrodipicolinate is converted into meso-diaminopimelate in a single enzymatic step; and (IV) the diaminopimelate-aminotransferase variant, in which tetrahydrodipicolinate is converted into meso-diaminopimelate in two steps. In addition to lysine, the pathways in this group also produce meso-DAP, which is an important metabolite on its own.
