Ichi chidzidzo chakanangana nealanine racemase gene (alr-2), iyo inobatanidzwa mukuumbwa kwe d-alanine inoumba musana wemadziro emadziro.Yakagadzikana alr-2 knockout mutant yeAeromonas hydrophila HBNUAh01 yakavakwa.Apo mutant wakawedzerwa ne d-alanine, kukura kwakanga kusina kukanganiswa;kushayikwa kwe d-alanine kwakakonzera kusungwa kwekukura kwemasero ane nzara mutant, asi kwete cell lysis.Hapana alanine racemase chiitiko chakaonekwa mutsika ye mutant.Pamusoro pezvo, membrane permeability assay yakaratidza kuwedzera kukuvadzwa kumadziro esero panguva yed-alanine nzara.Hapana kukuvadzwa kwakadaro kwakaonekwa mumhando yemusango panguva yetsika.Kuongorora uye kutapurirana maelectron microscopy ongororo yakaratidza kushomeka kwehamvuropu yesero uye kupera kwemadziro esero.Kudeuka kweUV-absorbing zvinhu kubva kune mutants kwakaonekwa zvakare.Saka, kugoneka kwechikamu chezvakachinja uye kuzvimiririra kwe d-alanine yekukura kwakaratidza kuti kusashanda kwealr-2 hakuisi iyo auxo trophic chinodikanwa che d-alanine.© FEMS 2015.
