Mapuloteni omwe angopezeka kumene amathandizira kuyenga bwino kwa Rare Earth
Mapuloteni omwe angopezeka kumene amathandizira kuyenga bwino kwa Rare Earth Mu pepala laposachedwa lofalitsidwa mu Journal of Biological Chemistry, ofufuza a ETH Zurich akufotokoza za kupezeka kwa lanpepsy, puloteni yomwe imamangiriza lanthanides - kapena zinthu zomwe sizipezeka padziko lapansi - ndikuzipatula ku mchere ndi zitsulo zina. Chifukwa cha kufanana kwawo ndi ayoni ena achitsulo, kuyeretsedwa kwa REE kuchokera ku chilengedwe kumakhala kovuta komanso kopanda ndalama m'malo ochepa.Podziwa izi, asayansi adaganiza zofufuza zida zachilengedwe zomangirira kwambiri ma lanthanides ngati njira zomwe zingapereke njira yakutsogolo. Gawo loyamba linali kuwunikanso kafukufuku wam'mbuyomu omwe akuwonetsa kuti chilengedwe chasintha mapuloteni osiyanasiyana kapena mamolekyu ang'onoang'ono kuti awononge lanthanides.Magulu ena ofufuza apeza kuti mabakiteriya ena, ma methylotrophs omwe amasintha methane kapena methanol, ali ndi ma enzyme omwe amafunikira lanthanides m'malo omwe akugwira ntchito.Chiyambireni kupezedwa koyamba pankhaniyi, kuzindikirika ndi mawonekedwe a mapuloteni omwe amakhudzidwa ndi kuzindikira, kutenga, ndi kugwiritsa ntchito kwa lanthanides, kwakhala gawo lofufuza lomwe likukula. Kuti adziwe ochita masewera a lanthanome, Jethro Hemmann ndi Philipp Keller pamodzi ndi ogwira nawo ntchito ku D-BIOL ndi labotale ya Detlef Günther ku D-CHAB, adaphunzira kuyankha kwa lanthanide ya obligate methylotroph Methylobacillus flagellatus. Poyerekeza ma proteome a maselo omwe amakula pamaso ndi kusakhalapo kwa lanthanum, adapeza mapuloteni angapo omwe sanagwirizane ndi kugwiritsa ntchito lanthanide. Pakati pawo panali puloteni yaying'ono ya ntchito yosadziwika, yomwe gululo tsopano linatcha lanpepsy.Mapuloteni opezeka m'thupi amavumbulutsa malo omwe amamangiriza lanthanides okhala ndi mawonekedwe apamwamba a lanthanum kuposa calcium yofanana ndi mankhwala. Lanpepsy imatha kulemeretsa lanthanides kuchokera ku yankho ndipo motero imakhala ndi kuthekera kopanga njira zopangira bioinspired pakuyeretsa kosatha kwa dziko losowa.
