MSMEG_0307 yog cov lus piav qhia raws li kev tswj hwm kev hloov pauv ntawm AraC protein tsev neeg thiab nyob ib sab ntawm arylamine N-acetyltransferase (nat) gene hauv Mycobacterium smegmatis, nyob rau hauv ib pawg noob, khaws cia hauv feem ntau ib puag ncig mycobacterial hom.Txhawm rau kom paub meej txog kev ua haujlwm ntawm AraC protein los ntawm nat operon hauv M. smegmatis, ob qhov kev khaws cia palindromic DNA motifs tau txheeb xyuas siv bioinformatics thiab kuaj cov protein khi siv electrophoretic txav txav mus los soj ntsuam nrog ib daim ntawv sib txuas ntawm AraC protein.Peb tau txheeb xyuas qhov tsim ntawm DNA: AraC protein complex nrog ib qho ntawm cov motifs nrog rau qhov muaj cov motif no hauv 20 loci thoob plaws tag nrho cov genome ntawm M. smegmatis, txhawb nqa lub neej ntawm AraC tswj regulon.Txhawm rau ua kom pom qhov cuam tshuam ntawm AraC hauv kev tswj hwm ntawm nat operon noob, nrog rau kom tau txais kev pom ntxiv rau nws txoj haujlwm, peb tau tsim ib qho ΔaraC mutant strain qhov twg araC noob tau hloov los ntawm hygromycin resi stance marker.Qib ntawm kev qhia ntawm nat thiab MSMEG_0308 noob tau qis-tswj nyob rau hauv ΔaraC strain thaum piv rau cov tsiaj qus hom uas qhia txog cov nyhuv activator ntawm AraC protein ntawm kev qhia ntawm nat operon noob.
