Rau Metalloprotein Hemerythrin, nqe lus uas tsis muaj tseeb yog: … Tsis zoo li hemoglobin, feem ntau hemerythrins tsis muaj kev sib koom tes rau oxygen.
Yuav ua li cas thaum O2 khi rau hemerythrin?
Ntawm no cov pa txuas nrog Fe yog oxidize vim tsim cov peroxide los ntawm oxygen thaum lwm yam Fe yuav oxidized vim Hu bonding ntawm hydroxide nrog cov peroxide. Yog li kev xaiv B thiab C yog qhov tseeb. Qhov kev sib tham no ntawm Cov kev hloov pauv (los ntawm AD muab hauv qab no) uas tshwm sim thaum O2 khi rau hemerythrin yog: (A) Ion atom yog oxidized.
Thaum O2 khi rau hemerythrin?
O2 binding mechanism
Tus uptake ntawm O2 los ntawm hemerythrin yog nrog los ntawm ob -electron oxidation ntawm qhov chaw sib txawv los tsim cov hydroperoxide (OOH−) complex.
Dab tsi yog qhov ua haujlwm ntawm hemerythrin?
Hemerythrin yog cov protein uas tsis yog heme siv los ntawm ob lub phyla ntawm marine invertebrates (sipunculids thiab brachiopods) rau kev hloov pauv oxygen thiab / lossis khaws cia. Nws txawv ntawm lwm cov pa oxygen-binding proteins (hemoglobin thiab hemocyanin) ob qho tib si nyob rau hauv cov saw polypeptide thiab hauv cov hlau complex siv los reversibly khi dioxygen.
Vim li cas hemoglobin hu ua metalloprotein?
Hemoglobin yog cov hlau uas muaj oxygen-transport metalloprotein hauv cov qe ntshav liab hauv cov tsiaj nyeg thiab lwm yam tsiaj. … Lub npehemoglobin yog sib txuas ntawm heme thiab globin, qhia txog qhov tseeb tias txhua lub subunit ntawm hemoglobin yog globular protein nrog ib pawg heme embedded.
