Makina a Mycobacterium smegmatis G (MbsG), l-lysine monooxygenase wodalira flavin, adafufuzidwa pansi pazikhalidwe zokhazikika komanso zofulumira pogwiritsira ntchito zotsatira za isotope zosungunulira, substrate analogs, pH ndi zosungunulira kukhuthala kwa viscosity monga ma probe amakanika.Zotsatira zikuwonetsa kuti l-lysine imamangiriza pamaso pa NAD (P) H, zomwe zimabweretsa kuchepa kwa mlingo wokhazikika wa kuchepetsa flavin.Kumanga kwa l-lysine sikukhala ndi mphamvu pa mlingo wa okosijeni wa flavin, womwe umapezeka mu sitepe imodzi popanda kuwona C4a-hydroperoxyflavin wapakatikati.Zofananazo zidatsimikiziridwa ndi ma analogi angapo apansipansi.Flavin oxidation ndi pH yodziyimira pawokha pomwe ma kcat/Km ndi kred/KD pH ma profiles a NAD(P)H amawonetsa ma pKa amodzi a ~6.0, ndikuchulukirachulukira pamene pH imachepa.Pa pH yochepa, puloteniyo imakhala yosagwirizanitsa, imapanga hydrogen peroxide ndi superoxide.Kusamutsa kwa Hydride ndikochepetsa pang'ono pa pH ya ndale ndipo kumakhala kocheperako pa low w pH.Kusinthasintha kwa viscosity viscosity zotsatira pa kcat/Km kwa NAD(P)H kunkawoneka pa pH ya ndale pomwe mphamvu yosungunulira yamadzimadzi imawonedwa pa pH yotsika.Pamodzi, zotsatira zimasonyeza njira yapadera yomwe kusintha kwa mlingo ndi pH-sensitive conformational kumachitika mu reductive theka-reaction, yomwe imakhudza mphamvu ya lysine hydroxylation.
