Research Abstract

To elucidate the biogenesis mechanism of built-in cofactors, the self-catalytic generation process of topaquinone cofactor (TPQ) was analyzed by frame-trapped X-ray crystallography, using copper-containing amine oxidase from Arthrobacter globiformis (AGAO). Then, X-ray structures of three intermediates during the TPQ biogenesis were determined, clearly showing the interactions with Cu^<2+> ion of precursor Tyr and its conformational charges during the biogenesis. Three tongued His residues coordinating Cu^<2+> ion were also substituted with Ala residue to clarify their roles on the TPQ biogenesis. The X-ray crystallographic and kinetic studies for these mutant enzymes demonstrate that precise position of Cu^<2+> ion is significantly important for the efficient TPQ biogenesis.
To generate artificial quinone cofactor in the active site of AGAO, D298K mutant AGAO was prepared by site-directed mutagenesis. When D298K was activated by incubation with Cu^<2+> ion, a unique chromophore with λ_<***> of 450 nm, which is distinct from that of TPQ(λ_<***>=480 nm) in the wild type, was formed. By careful refinements in the X-ray crystallography of bolo D298K, it was found that C2 atom of TPQ ring is covalently bound to N_ε atom of Lys298 through imino double bond. Although the formation of lysine tyrosyl quinone would be expected, the identified quinone-like structure is a novel cofactor generated autocatalytically. Further, to produce a composite-type new quinone enzyme, Y382C mutant was produced. By incubating Y382C with mercaptophenol and Cu^<2+> ion, despite of undetectable UV/vis spectral changes, the low but apparent catalytic activity using phenethylamine was detected. Because no catalytic activity was detected in the absent of Cu^<2+>, it is possible that the biogenesis reaction forms any cofactor, resulting in the catalytic activity.
