Olu pho nonongo lujolise kwi-alanine racemase gene (alr-2), ebandakanyeka kwi-synthesis ye-d-alanine eyenza umqolo wodonga lweseli.I-alr-2 knockout mutant ezinzileyo ye-Aeromonas hydrophila HBNUAh01 yakhiwa.Xa i-mutant yongezwa nge-d-alanine, ukukhula kwakungachaphazeleki;ukuvinjwa kwe-d-alanine kubangele ukubanjwa kokukhula kweeseli eziguqukayo ezilambileyo, kodwa kungekhona i-cell lysis.Akukho msebenzi we-alanine racemase ufunyenwe kwinkcubeko ye-mutant.Ukongeza, uvavanyo lwe-membrane permeability lubonise ukonyuka komonakalo kudonga lweseli ngexesha lendlala ye-d-alanine.Akukho monakalo onjalo wabonwa kuhlobo lwasendle ngexesha lenkcubeko.Ukuskena kunye nokusasaza i-electron microscopy uhlalutyo olutyhileyo ukusilela kwemvulophu yeseli kunye nokugqobhozwa kodonga lweseli.Ukuvuza kwezinto ezifunxa i-UV kwizinto eziguqukayo nazo zabonwa.Ke, ukwenzeka kwenxalenye yeenguqu kunye nokuzimela kwabo kwe-d-alanine ekukhuleni kubonise ukuba ukungasebenzi kwe-alr-2 akunyanzeli imfuno ye-auxo trophic ye-d-alanine.© FEMS 2015.
