Uburyo bwa Mycobacterium smegmatis G (MbsG), buterwa na l-lysine monooxygenase iterwa na flavin, bwakozweho ubushakashatsi bwihuse kandi bwihuse hakoreshejwe ingaruka za kinetic isotope yibanze, insimburangingo, pH hamwe ningaruka ziterwa nubukonje nkibisubizo byubukanishi.Ibisubizo byerekana ko l-lysine ihuza mbere ya NAD (P) H, biganisha ku kugabanuka kw'igipimo gihoraho cyo kugabanya flavin.Guhuza l-lysine nta ngaruka bigira ku gipimo cya okiside ya flavin, ibaho mu ntambwe imwe itabanje kureba C4a-hydroperoxyflavin hagati.Ingaruka nkizo zagenwe hamwe na substrate nyinshi.Flavin okiside ni pH yigenga mugihe kcat / Km na kred / KD pH imyirondoro ya NAD (P) H yerekana indangagaciro imwe ya pKa ya ∼6.0, hamwe nibikorwa byiyongera uko pH igabanuka.Kuri pH yo hepfo, enzyme iba idafunze, ikabyara hydrogen peroxide nyinshi na superoxide.Hydride ihererekanya igice igabanya igipimo kuri pH itabogamye kandi ihinduka cyane igipimo kuri lo w pH.Ingaruka mbi ya viscosity ya kcat / Km kuri NAD (P) H yagaragaye kuri pH idafite aho ibogamiye mugihe ingaruka zisanzwe zo kwangirika zagaragaye kuri pH yo hepfo.Hamwe na hamwe, ibisubizo byerekana uburyo budasanzwe aho impinduka zigabanya igipimo na pH-zihuza impinduka zibaho muguhindura igice-reaction, bigira ingaruka kumikorere ya hydroxylation ya lysine.
