Kafukufukuyu adayang'ana pa jini ya alanine racemase (alr-2), yomwe imakhudzidwa ndi kaphatikizidwe ka d-alanine yomwe imapanga msana wa khoma la cell.Khola lokhazikika la alr-2 knockout mutant la Aeromonas hydrophila HBNUAh01 linapangidwa.Pamene mutant adawonjezeredwa ndi d-alanine, kukula sikunakhudzidwe;Kuperewera kwa d-alanine kunayambitsa kumangidwa kwa maselo omwe ali ndi njala, koma osati cell lysis.Palibe ntchito ya alanine racemase yomwe idapezeka mu chikhalidwe cha mutant.Kuphatikiza apo, kuyesa kwa membrane permeability kunawonetsa kuwonongeka kwa khoma la cell panthawi ya njala ya d-alanine.Palibe kuwonongeka kotereku komwe kunawonedwa mumtundu wakuthengo panthawi yachikhalidwe.Kusanthula ndi kufalitsa ma electron microscopy kusanthula kwavumbulutsa kuperewera kwa envulopu ya cell ndi kuphulika kwa khoma la cell.Kutayikira kwa zinthu zomwe zimayamwa UV kuchokera ku zosinthika zidawonedwanso.Chifukwa chake, kutheka kwapang'ono kwa osinthika komanso kudziyimira pawokha kwa d-alanine kuti akule kukuwonetsa kuti kusakhazikika kwa alr-2 sikukhazikitsa kufunikira kwa auxo trophic kwa d-alanine.© FEMS 2015.
