Masayendisiti akagadzira enzyme iyo inogona kuwedzera mwero wekuora kwepurasitiki nechitanhatu. Enzyme inowanikwa mumarara mabhakitiriya eimba anodya epurasitiki chikafu chinoshandiswa chakabatana pamwe nePETase kukurumidza kuora kwepurasitiki.
Katatu chiitiko cheiyo super enzyme
Chikwata chakagadzira yakasikwa PETase enzyme murabhoritari, iyo inogona kukurumidza kuora kwePET neinenge 20%. Ikozvino, iyo imwechete transatlantic timu yakasanganisa PETase neayo "mudiwa" (enzyme yechipiri inonzi MHETase) kuburitsa yakatowanda kuvandudza: kungosanganisa PETase neMHETase kunogona kuwedzera mwero wePET kuora Kaviri iyo, uye kugadzira kubatana pakati pemaviri maenzyme kugadzira "super enzyme" iyo inowedzera chiitiko ichi.
Chikwata ichi chinotungamirwa nemusayendisiti akagadzira PETase, Muzvinafundo John McGeehan, director weCentre for Enzyme Innovation (CEI) kuYunivhesiti yePortsmouth, naDr.Gregg Beckham, muongorori mukuru kuNational Renewable Energy Laboratory (NREL). MuU.S.
Muzvinafundo McKeehan vakati: Ini naGreg tiri kutaura pamusoro pekuti PETase inokanganisa sei nzvimbo yepurasitiki, uye MHETase inoipamhazve, saka zvakajairwa kuona kana tichigona kuzvishandisa pamwechete kutevedzera zvinoitika muchisiko. "
Ma enzymes maviri anoshanda pamwechete
Pakutanga kuyedza kwakaratidza kuti aya ma enzymes anokwanisa kushanda zvirinani pamwechete, saka vaongorori vakasarudza kuyedza kuzvibatanidza panyama, sekungobatanidza maviri Pac-Man netambo.
"Basa rakawanda rakaitwa pamativi ese eAtlantic, asi zvakafanira kuedza - tinofara kuona kuti enzyme yedu nyowani inomhanyisa zvakapetwa katatu kupfuura enzyme yakazvimirira yakasununguka, ichivhura nzira nyowani dzekuenderera mberi nekuvandudza. " McGeehan akaenderera mberi.
Ose PETase uye ichangobatanidzwa MHETase-PETase inogona kushanda nekugaya PET mapurasitiki uye kuidzosera kune yayo yekutanga chimiro. Nenzira iyi, mapurasitiki anogona kugadzirwa nekushandiswazve zvisina mugumo, nokudaro tichideredza kuvimba kwedu nezvinhu zvepasi zvakadai semafuta negasi rechisikigo.
Muzvinafundo McKeehan vakashandisa synchrotron muOxfordshire, iyo inoshandisa maX-ray, ayo akasimba zvakapetwa kagumi kupfuura zuva, semicroscope, inokwana kucherechedza maatomu ega ega. Izvi zvakabvumidza timu yekutsvagisa kugadzirisa 3D dhizaini yeMHETase enzyme, nokudaro ichivapa iwo mamorekuru chirongwa kuti vatange kugadzira nekukurumidza enzyme masystem.
Iyi tsvagiridzo nyowani inosanganisa masystem, computational, biochemical uye bioinformatics nzira kuburitsa mamorekisi kunzwisisa kweayo mamiriro uye mashandiro. Uku kutsvagisa ibasa rakakura reboka rinosanganisira vesaenzi veese matanho emabasa.
