GENERAL INFORMATION

UNIPROT
COMMENTARY
LITERATURE
physiological function
-
in Escherichia coli, the major enzymes with N-succinyl-L,L-diaminopimelate aminotransferase (SDAP-AT) activity in lysine synthesis are ArgD, AstC, and SerC. Lysine availability does not regulate synthesis of the major SDAP-ATs. Complementation analysis of mutants lacking aminotransferases shows that the SDAP-ATs and alanine aminotransferases are exceptionally redundant, and this redundancy may ensure peptidoglycan synthesis

LITERATURE
diffration to 2.0 A resolution. The orthorhombic crystals contain one functional dimer in the asymmetric unit. The homodimer displays the typical S-shape of class I pyridoxal 5'-phosphate-binding proteins. The two active sites of the dimer both feature an internal aldimine with the co-factor pyridoxal 5'-phosphate covalently bound to the Lys232, although neither substrate nor cofactor has been added during protein production, purification and crystallization. Nine water molecules are conserved in the active site and form an intricate hydrogen-bonding network with the co-factor and the surrounding amino acid residues
