Mechanismus Mycobacterii smegmatis G (MbsG), flavin-dependens l-lysinus monooxygenas, sub stabilitate et celeri reactionis condicione pervestigata est per effectus isotopes primarias et solvendos, analogas substratas, pH et viscositatem solvendo effectibus ut mechanisticorum explorationum.Eventus suggerunt l-lysinum ligare ante NAD(P)H, qui diminutionem in rate constantem ad reductionem flavinam ducit.ligamentum l-lysinum effectum non habet in rate oxidationis flavini, quod fit in processu unius gradus sine observatione intermedii C4a-hydroperoxyflavini.Similia effectus cum pluribus subiectis analogis determinati sunt.Flavin oxidatio pH independens est dum profiles kcat/Km et kred/KD pH pro NAD(P)H exhibent, valores 6.0 singulares pKa, augente actione sicut pH decrescente.In pH inferiori, enzyme plus unco efficitur, peroxide et superoxide plus producens.Hydride translatio partim rate limitans ad pH neutrum est et plus rate limitat ad lo w pH.Viscositas inversa solvens effectum in kcat/Km pro NAD(P)H in neutra pH observatum est, quum normalis effectus viscositas solvens in inferiore pH observatus est.Una, eventus demonstrant singularem mechanismum ubi mutatio rate limitans et pH-sensitiva conformationis occurrit in media reactione reductiva, quae efficaciam hydroxylationis lysinae afficit.
