| Type: | Domain | Name: | PLP-binding barrel |
| Description: | This entry represents the PLP (pyridoxal 5'-phosphate)-binding barrel that can be found at the N terminus of alanine racemase-like proteins and some uncharacterised proteins.The molecular structure of alanine racemase from Bacillus stearothermophiluswas determined by X-ray crystallography to a resolution of 1.9 A []. The alanine racemase monomer is composed of two domains, an eight-stranded alpha/beta barrel at the N terminus, and a C-terminal domain essentially composed of beta-strands. The pyridoxal 5'-phosphate (PLP) cofactor lies in and above the mouth of the alpha/beta barrel and is covalently linked via an aldimine linkage to a lysine residue, which is at the C terminus of the first beta-strand of the alpha/beta barrel. | Short Name: | PLP-binding_barrel |
