Iyo nzira yeMycobacterium smegmatis G (MbsG), flavin-inotsamira l-lysine monooxygenase, yakaferefetwa pasi peyakagadzikana-mamiriro uye nekukurumidza kuita mamiriro uchishandisa yekutanga uye solvent kinetic isotope mhedzisiro, substrate analogs, pH uye solvent viscosity mhedzisiro se mechanistic probes.Mhedzisiro yacho inoratidza kuti l-lysine inosunga pamberi peNAD (P) H, izvo zvinotungamira kudzikira kwechiyero chenguva dzose yekuderedza flavin.L-lysine binding haina simba pachiyero cheflavin oxidation, iyo inowanikwa mune imwe-nhanho nzira pasina kuonekwa kweC4a-hydroperoxyflavin yepakati.Mamiriro akafanana akatemerwa aine akati wandei substrate analog.Flavin oxidation ndeye pH yakazvimirira nepo kcat/Km uye kred/KD pH profiles yeNAD(P)H inoratidza imwechete pKa kukosha kwe ~6.0, nekuwedzera chiitiko sezvo pH inoderera.Pazasi pH, iyo enzyme inova isina kubatanidzwa, ichigadzira yakawanda hydrogen peroxide uye superoxide.Kufambiswa kweHydride kune chikamu-kumisikidza pane kwayakarerekera pH uye inova yakawanda-inomisa chiyero papasi pe pH.Inverse solvent viscosity effect pa kcat/Km yeNAD(P)H yakaonekwa pane kwayakarerekera pH asi yakajairika solvent viscosity effect yakaonekwa pazasi pH.Pamwe chete, mhedzisiro inoratidza yakasarudzika nzira apo chiyero-chinogumira uye pH-sensitive conformational shanduko inoitika mune reductive hafu-reaction, iyo inokanganisa kushanda kwe lysine hydroxylation.
