Protheine e sa tsoa sibolloa e tšehetsa tlhoekiso e sebetsang ea Rare Earth

mohloli: morafo

Ka pampiri ea morao-rao e hatisitsoeng ho Journal of Biological Chemistry, bafuputsi ba ETH Zurich ba hlalosa ho sibolloa ha lanpepsy, protheine e tlamang li-lanthanides ka ho khetheha - kapa likarolo tse sa tloaelehang tsa lefats'e - le ho li khetholla ho liminerale le litšepe tse ling.

Ka lebaka la ho tšoana ha tsona le li-ion tse ling tsa tšepe, ho hloekisoa ha REE ho tloha tikolohong ho boima ebile ho na le moruo libakeng tse 'maloa feela.Ka ho tseba sena, bo-rasaense ba ile ba etsa qeto ea ho hlahloba lisebelisoa tsa likokoana-hloko tse nang le lintlha tse phahameng tse tlamang li-lanthanides e le mekhoa e ka fanang ka tsela ea pele.

Mohato oa pele e ne e le ho hlahloba liphuputso tse fetileng tse bontšang hore tlhaho e fetohile mefuta e sa tšoaneng ea liprotheine kapa limolek'hule tse nyenyane ho senya lanthanides.Lihlopha tse ling tsa lipatlisiso li fumane hore libaktheria tse ling, methylotrophs tse fetolang methane kapa methanol, li na le li-enzyme tse hlokang lanthanides libakeng tsa tsona tse sebetsang.Ho tloha ha li sibolloa tsa pele lefapheng lena, ho tsebahatsa le ho khetholla liprotheine tse amehang ho utloeng, ho nkeng le ho sebelisoa ha lanthanides, e se e le lefapha le hlahang la lipatlisiso.

Ho tsebahatsa batšoantšisi ba libuka tsa lanthanome, Jethro Hemmann le Philipp Keller hammoho le basebetsi-'moho le D-BIOL le laboratori ea Detlef Günther e D-CHAB, ba ithutile karabo ea lanthanide ea methylotroph Methylobacillus flagellatus.

Ka ho bapisa proteome ea lisele tse hōlileng ka boteng le ho ba sieo ha lanthanum, ba fumane liprotheine tse 'maloa tse neng li sa amane le tšebeliso ea lanthanide.

Har'a tsona ho ne ho e-na le protheine e nyenyane ea tšebetso e sa tsejoeng, eo joale sehlopha se ileng sa e bitsa lanpepsy.In vitro characterization ea protheine e senotse libaka tse tlamang tsa lanthanides tse nang le boleng bo phahameng ba lanthanum holim'a calcium e tšoanang le lik'hemik'hale.

Lanpepsy e khona ho ruisa lanthanides ho tsoa tharollong 'me kahoo e na le monyetla oa ho nts'etsapele lits'ebetso tsa bioinspired bakeng sa tlhoekiso e tsitsitseng ea lefatše le sa tloaelehang.
