Indlela ye-Mycobacterium smegmatis G (MbsG), i-l-lysine monooxygenase encike ku-flavin, yaphenywa ngaphansi kwezimo eziqinile nezisheshayo zokusabela kusetshenziswa imiphumela eyinhloko ne-solvent ye-isotope ye-kinetic, ama-substrate analogue, i-pH kanye nemiphumela ye-viscosity ye-solvent njenge-probes yemishini.Imiphumela iphakamisa ukuthi i-l-lysine ibophezela ngaphambi kwe-NAD(P)H, okuholela ekwehleni kwesilinganiso esingaguquki sokunciphisa i-flavin.Ukubophezela kwe-l-lysine akunawo umthelela kuzinga le-flavin oxidation, eyenzeka ngesinyathelo esisodwa ngaphandle kokubonwa kwe-C4a-hydroperoxyflavin ephakathi.Imiphumela efanayo yanqunywa ngama-analogue ambalwa e-substrate.I-Flavin oxidation i-pH ezimele kuyilapho iphrofayili ye-kcat/Km ne-kred/KD pH ye-NAD(P)H ibonisa amanani e-pKa eyodwa angu-∼6.0, nomsebenzi okhulayo njengoba i-pH iyancipha.Nge-pH ephansi, i-enzyme iba ingahlangani, ikhiqize i-hydrogen peroxide eyengeziwe ne-superoxide.Ukudluliswa kwe-Hydride kukhawulela isilinganiso ngokwengxenye ku-pH engathathi hlangothi futhi kuba nomkhawulo owengeziwe nge-pH ephansi.Umphumela we-viscosity we-solvent ephambene ku-kcat/Km ye-NAD(P)H ubonwe nge-pH emaphakathi kanti umphumela we-viscosity we-solvent ojwayelekile ubonwe ku-pH ephansi.Ndawonye, imiphumela ikhombisa indlela eyingqayizivele lapho uguquko lokunciphisa izinga kanye ne-pH-sensitive conformational lwenzeka ku-reductive half-reaction, ethinta ukusebenza kahle kwe-lysine hydroxylation.
