ALANINE RACEMASE COMPLEXED WITH ALANINE PHOSPHONATE
Overview
(R)-1-Aminoethylphosphonic acid (L-Ala-P), a synthetic L-alanine analogue, has antibacterial activity and is a time-dependent inactivator of all, purified Gram-positive bacterial alanine racemases that have been tested., L-Ala-P forms an external aldimine with the bound pyridoxal 5'-phosphate, (PLP) cofactor, but is neither racemized nor efficiently hydrolyzed. To, understand the structural basis of the inactivation of the enzyme by, L-Ala-P, we determined the crystal structure of the complex between, L-Ala-P and alanine racemase at 1.6 A resolution. The cofactor derivative, in the inhibited structure tilts outward from the protein approximately 20, degrees relative to the internal aldimine. The phosphonate oxygens are, within hydrogen bonding distance of four amino acid residues and two ... [(full description)]
