Abahanga mu Budage biga imiterere ya Sars-Cov-2 virusi ya 3 yakoresheje icyitegererezo cya 3D. Impumuro ya molekirus ya coronamenye izafasha mugushakisha ingirakamaro kugirango irwanye ibikoresho bya pathogen.
Ibinyabuzima bikomoka muri Würzburg Andrea Thorn kuva intangiriro yicyorezo ni kugerageza gusobanura ibice bya poroteyine kugiti cye byabanyeshuri-cov-2. Ibi birakenewe kugirango abayifite inkingo n'ibiyobyabwenge ku isi babone uburyo bwo kurinda kwandika berliner Zeitung. Mu kiganiro n'ibitabo, inzobere yavuze ko murakoze gusobanukirwa neza imiterere ya molekile ya coronavirus no kuba hari moderi zabo, urashobora kumenya uburyo virusi ikora. Kurugero, niba afashe selile yumuntu akatuma itanga virusi nyinshi noneho buri ntambwe yari ikozwe muri molekile ya proteyine. Kubwibyo, guhagarika iyi molekile za proteyine bisobanura guhagarika indwara.
SARS-COV-2 isa ite?
Coronamenye ntabwo azengurutse. Birasa nkisabune mubyifuzo bihoraho. Igice cyo hanze ni cyoroshye cyoroshye kandi kigizwe na acty acty imeze nkigisabune. Rero, isabune irashobora gushonga rwose igikonoshwa cya virusi - mugihe amaboko yoza igihe kirekire. Igice cyo hanze gitwikiriwe nicyitwa Spike cyemerera virusi kwinjira kurugero mumacumba. Ariko kuba benshi bita virusi mubyukuri mubyukuri ari "ubwoko bwo gutwara" muri Vision. Imbere itwara ibikoresho bya genetique kuri molekile 28. Byinshi muribyo byubakwa bwa mbere muri selile yo gutwarwa kugirango bihindure ikintu cyo gukora virusi.Benshi bizera ko virusi idashobora kugaragara. Bashobora no kutamenya ko amashusho yamabara yerekanwe mubitangazamakuru ari amashusho ya virusi. Virusi n'inzaga ntibigaragara. Ati: "Abantu ntibabona benshi bapfuye ntibabona amashami menshi yo gukwirakwira kubera ko mu gusura. Ni n'imwe mu mpamvu natwe twaremye kandi ducapura
Kugira ngo umuntu agira ibyago byinshi, "umuhanga mu binyabuzima yabivuze.
Nigute Gusobanura Inzego za Molekori
Abahanga ntibapima virusi yose, ahubwo ni molekile zabo gusa. Intego y'abinyabuzima mu bihangange ni ugushakisha imwe mu bantu 28 batandukanye b'ibice bya SARS-COV-2. Ikindi gikorwa nukugata poroteyine. Ikariri nubunini bwa cumi na kimwe cya milimetero kandi bigizwe na molekire y'ibihumbi. Noneho iyi kristu ipimwa ukoresheje x-rays ku giti cyitwa Synchrotron yihuta yihuta yihuta nka Besy II i Berlin. Aya makuru kandi atwemerera kubaka icyitegererezo cya gatatu cya molekile yakozwe.
Mu rwego rwo kwiga, icyitegererezo cyakozwe hashingiwe ku bipimo byabonetse biragenzurwa kandi byanonosowe. Abagize itsinda rya Andrea Thorn bakurikirwa na buri Apom yerekanwe kuri monitor ya 3D. Kwororoka bya bagiteri birashobora gufata kuva kumezi 1 kugeza kuri 36 hamwe no gukora isuku kugeza igihe izakora. Egg poroteyiri kaburimbo kuva kumezi 1 kugeza 24. Gupima muri Synchrotron bifata iminota itatu. Gukusanya amakuru hamwe ninteko yinzego zifashishijwe ingingo zidasanzwe zifata mucyumweru kugeza kumezi ane umuhanga usobanurwa.
Kugeza ubu, abahanga bapimye moleki 17 28 za virusi. Mugihe imiterere itari myinshi - ibisobanuro bifata ibyumweru byinshi cyangwa ukwezi - ariko izi nyubako zirashobora kugereranywa kuri mudasobwa. Kuva muri make ibihumbi gusa muri molekile barahindurwa. Nyuma yicyorezo, umubare wubushakashatsi wagabanutse cyane kandi ntibagiterwa inkunga. Umuhanga mu binyabuzima mu binyabuzima yemera: Niba ubushakashatsi bwa Sars-COV-2 bwakozwe buri gihe abahanga mu bya siyansi bari kugira ubumenyi bwinshi kuri Coronavirusi. Byaba ari byiza cyane kandi biyemerera kwitegura neza icyorezo gikurikira.
