Vim li ntawd, quaternary qauv tsuas yog siv rau cov protein ntau subunit; uas yog, cov proteins ua los ntawm ib tug ntau tshaj ib tug polypeptide saw. Cov proteins uas ua los ntawm ib qho polypeptide yuav tsis muaj quaternary qauv.
Dab tsi ua rau quaternary qauv?
Thaum cov subunits tuaj ua ke, lawv muab cov protein rau nws cov qauv quaternary. … Feem ntau, tib hom kev sib cuam tshuam uas ua rau cov qauv tertiary (feem ntau tsis muaj kev sib cuam tshuam, xws li hydrogen bonding thiab London dispersion rog) kuj tuav cov subunits ua ke los muab cov qauv quaternary.
quaternary qauv txiav txim li cas?
Cov qauv quaternary feem ntau yog txiav txim los ntawm X-ray crystallography, raws li tau piav qhia yav dhau los. Txawm li cas los xij, thaum cov ntaub ntawv crystallographic nyuaj los yog tsis tuaj yeem sib sau ua ke, electron microscopy tau muab qee qhov qhia rau quaternary qauv.
Cov proteins twg muaj cov qauv quaternary?
Piv txwv ntawm cov proteins nrog cov qauv quaternary suav nrog hemoglobin, DNA polymerase, thiab ion channels. Enzymes tsim los ntawm subunits nrog ntau lub luag haujlwm yog qee zaum hu ua holoenzymes, uas qee qhov chaw yuav raug hu ua kev tswj hwm subunits thiab lub luag haujlwm tseem ceeb yog hu ua catalytic subunit.
Vim li cas cov proteins muaj cov qauv quaternary?
Quaternary qauv yog hais txog kev npaj thiab kev sib cuam tshuam ntawm subunits uas suav nrogib protein. … Ib lub xovtooj ntawm tes yuav txuag tau cov peev txheej tseem ceeb hauv kev tsim cov protein ntau los ntawm kev rov ua cov synthesis ntawm ob peb polypeptide chains ntau zaus es tsis yog synthesizing ib txoj hlua polypeptide ntev heev.
