Function
DBD23_ASPOR Has an absolute substrate specificity for 2,3-DHBA.
Publication Abstract from PubMed
Broad substrate tolerance and excellent regioselectivity, as well as independence from sensitive cofactors established benzoic acid decarboxylases from microbial sources as efficient biocatalysts. Robustness under process conditions makes them particularly attractive for preparative-scale applications. The divalent metal-dependent enzymes are capable of catalyzing the reversible non-oxidative (de)carboxylation of a variety of electron-rich (hetero)aromatic substrates analogously to the chemical Kolbe-Schmitt reaction. Elemental mass spectrometry supported by crystal structure elucidation and quantum chemical calculations verified the presence of a catalytically relevant Mg 2+ complexed in the active site of 2,3-dihydroxybenoic acid decarboxylase from Aspergillus oryzae (2,3-DHBD_ Ao ). This unique example with respect to the nature of the metal is in contrast to mechanistically related decarboxylases, which generally bear Zn 2+ or Mn 2+ as the catalytically active metal.
