Poroteyine nshya yavumbuwe ishyigikira gutunganya neza isi idasanzwe
Poroteyine nshya yavumbuwe ishyigikira gutunganya neza isi idasanzwe Mu mpapuro ziherutse gusohoka mu kinyamakuru cya Biologiya Chemistry, abashakashatsi bo muri ETH Zurich basobanura ivumburwa rya lanpepsy, poroteyine ihuza cyane na lanthanide - cyangwa ibintu bidasanzwe ku isi - ikanabavangura mu yandi mabuye y'agaciro n'amabuye y'agaciro. Kuberako bisa nibindi byuma ion, kweza REE kubidukikije biragoye kandi byubukungu ahantu hamwe gusa.Abashakashatsi babimenye, bahisemo gushakisha ibikoresho byibinyabuzima bifite umwihariko wa lanthanide nkuburyo bushobora gutanga inzira igana imbere. Intambwe yambere kwari ugusubiramo ubushakashatsi bwibanze bwerekana ko ibidukikije byahinduye poroteyine zitandukanye cyangwa molekile nto kugirango zivemo lanthanide.Andi matsinda y’ubushakashatsi yavumbuye ko bagiteri zimwe na zimwe, methylotrophs zihindura metani cyangwa methanol, zifite imisemburo isaba lanthanide aho ikora.Kuva ibintu byavumbuwe bwa mbere muri uru rwego, kumenya no kuranga poroteyine zigira uruhare mu kumva, gufata, no gukoresha lanthanide, byahindutse ubushakashatsi bugaragara. Kugirango hamenyekane abakinnyi bashya muri lanthanome, Jethro Hemmann na Philipp Keller hamwe nabafatanyabikorwa ba D-BIOL na laboratoire ya Detlef Günther muri D-CHAB, bakoze ubushakashatsi kuri lanthanide ya methylotroph Methylobacillus flagellatus. Mugereranije proteome ya selile ikura imbere ya lanthanum idahari, basanze proteine nyinshi zidafitanye isano no gukoresha lanthanide. Muri byo harimo proteine ntoya yimikorere itazwi, ubu itsinda ryise lanpepsy.Muri vitro iranga poroteyine yerekanye imbuga za lanthanide zifite umwihariko wa lanthanum hejuru ya calcium isa na chimique. Lanpepsy ishoboye gukungahaza lanthanide ikemura igisubizo bityo ikagira ubushobozi bwo guteza imbere inzira ya bioinspired kugirango isukure rirambye ryisi idasanzwe.
