Myoglobin tsuas muaj ib lub subunit xwb ces nws tsis muaj quaternary qauv . Feem ntau cov proteins yog cov lus ces lawv muaj thawj, theem nrab, thiab tertiary qauv , mas tsis yog quaternary qauv.
Ua li no, puas yog tag nrho cov proteins muaj cov qauv quaternary?
Tag nrho cov protein muaj thawj, theem nrab thiab tertiary cov qauv tab sis quaternary qauv tsuas yog tshwm sim thaum a protein ntau yog tsim los ntawm ob los yog ntau dua polypeptide chains. Lub folding ntawm cov proteins tseem tau tsav thiab txhawb nqa los ntawm kev tsim ntawm ntau daim ntawv cog lus ntawm qhov sib txawv ntawm cov saw hlau.
Ib tug kuj yuav nug, ua li cas koj paub yog hais tias ib tug protein muaj ib tug quaternary qauv? Quaternary qauv yog kev sib cuam tshuam ntawm ob lossis ntau dua folded polypeptides. Ntau cov proteins xav tau kev sib dhos ntawm ob peb polypeptide subunits ua ntej lawv ua haujlwm. Yog qhov kawg protein yog ua los ntawm ob subunits, lub protein yog hais tias yog ib tug dimer.
Kuj Paub, cov proteins twg tuaj yeem ua tiav quaternary qauv?
Ntau cov proteins Qhov tseeb yog cov sib dhos ntawm ntau cov saw hlau polypeptide. Cov quaternary qauv hais txog tus naj npawb thiab kev npaj ntawm cov protein ntau subunits nrog kev hwm rau ib leeg. Piv txwv ntawm cov proteins nrog quaternary qauv suav nrog hemoglobin, DNA polymerase, thiab ion channels.
Dab tsi ua rau lub quaternary qauv?
Los ntawm txhais, quaternary qauv yog qhov kev npaj ntawm ntau tshaj ib tug protein molecule nyob rau hauv ib tug multi-subunit complex. Cov nomenclature ntawm no tuaj yeem nkag siab me ntsis vim tias peb hu rau ib leeg polypeptide saw protein yog tias nws tuaj yeem ua haujlwm ntawm nws tus kheej. Daim duab no qhia txog cov protein uas yog ua ntawm ntau cov protein subunits.
