Publication Abstract from PubMed
l-Amino acid deaminase from Proteus myxofaciens (PmaLAAD) is a membrane flavoenzyme that catalyzes the deamination of neutral and aromatic l-amino acids into alpha-keto acids and ammonia. PmaLAAD does not use dioxygen to re-oxidize reduced FADH2 and thus does not produce hydrogen peroxide; instead, it uses a cytochrome b-like protein as an electron acceptor. Although the overall fold of this enzyme resembles that of known amine or amino acid oxidases, it shows the following specific structural features: an additional novel alpha+beta subdomain placed close to the putative transmembrane alpha-helix and to the active-site entrance; an FAD isoalloxazine ring exposed to solvent; and a large and accessible active site suitable to bind large hydrophobic substrates. In addition, PmaLAAD requires substrate-induced conformational changes of part of the active site, particularly in Arg-316 and Phe-318, to achieve the correct geometry for catalysis. These studies are expected to pave the way for rationally improving the versatility of this flavoenzyme, which is critical for biocatalysis of enantiomerically pure amino acids.
