Kitagawa M, Ito N, Matsumoto Y, Saito M, Tamura T, Kusakabe H, et al.
J Struct Biol X . 2021 Feb; 5:100044. PMID: 33554108
Harmuful proteins are usually synthesized as inactive precursors and are activated by proteolytic processing. l-Amino acid oxidase (LAAO) is a flavoenzyme that catalyzes the oxidative deamination of l-amino acid to...

Kondo H, Kitagawa M, Matsumoto Y, Saito M, Amano M, Sugiyama S, et al.
Protein Sci . 2020 Sep; 29(11):2213-2225. PMID: 32894626
l-Lysine oxidase (LysOX) is a FAD-dependent homodimeric enzyme that catalyzes the oxidative deamination of l-lysine to produce α-keto-ε-aminocaproate with ammonia and hydrogen peroxide. LysOX shows strict substrate specificity for l-lysine,...
