Txhua cov amino acids muaj nyob hauv α-helices, tab sis glycine thiab proline tsis tshua muaj, vim lawv ua rau α-helix destabilizes. Glycine raug zam los ntawm ntau yam kev txwv tsis pub vim nws tsis muaj β carbon. … Proline, ntawm qhov tod tes, yog nruj heev.
Yuav ua li cas cov amino acid tsis pom nyob rau hauv alpha helices?
Proline tsis pom nyob rau hauv alpha helical qauv ntawm cov proteins, vim nws muaj cov qauv tshwj xeeb cyclic (nws yog ib qho imino acid tsis yog amino acid) m hom qauv thib ob muaj tshwj xeeb dav thiab tus naj npawb ntawm cov amino acids residues / tig. Yog li ntawd proline yog txiav txim siab raws li alpha helical breaker.
Vim li cas glycine yog alpha helix breaker?
Proline thiab glycine qee zaum hu ua "helix breakers" vim lawv cuam tshuam qhov tsis tu ncua ntawm α helical qaum conformation; Txawm li cas los xij, ob qho tib si muaj peev xwm sib txawv txawv thiab feem ntau pom nyob rau hauv lem.
glycine nyob rau hauv alpha helix nyob qhov twg?
Muaj peb txoj haujlwm hauv helix-tig-helix motif uas tau txais kev txuag zoo heev. Ib qho alanine feem ntau pom ntawm txoj hauj lwm 5 hauv thawj α helix; ib glycine pom ntawm txoj hauj lwm 9, thawj txoj hauj lwm ntawm tig; thiab valine lossis isoleucine feem ntau pom nyob rau ntawm txoj haujlwm 15 hauv qhov thib ob α helix.
Puas glycine residues feem ntau pom nyob rau hauv alpha helices?
Glycine, nrog nws ntau qhov ua tau zoo ntawm cov saw hlau, yog kuj tsis tshua pom muaj nyob hauv helices. Paub tias yuav ua li cas cov amino acid yuav tshwm sim hauv alpha helix (lub npe hu ua helix propensities), nws muaj peev xwm kwv yees qhov twg helices tshwm sim hauv cov protein ntau.
Pom zoo:
Kev hloov pauv feem ntau tsis zoo vim li cas lossis vim li cas ho tsis?
Feem ntau ntawm kev hloov pauv yog nruab nrab ntawm lawv cov teebmeem ntawm cov kab mob uas lawv tshwm sim. Kev hloov pauv tau zoo tuaj yeem ua ntau dua los ntawm kev xaiv ntuj. Kev hloov pauv tsis zoo yuav ua rau muaj kab mob caj ces lossis mob qog noj ntshav .
Vim li cas ho tsis pom kev tsis pom kev tseem ceeb?
Vim li cas thiaj tseem ceeb Qhov kev tsis ncaj ncees tom qab tau txais hauv txoj kev los ntawm kev cuam tshuam cov ntaub ntawv sab hauv peb muaj peb qhov kev kwv yees yav dhau los Qhov no tuaj yeem ua rau muaj kev ntseeg siab dhau los yav tom ntej uas ua rau muaj kev pheej hmoo kev txiav txim siab nrog cov txiaj ntsig tsis zoo.
Muaj pes tsawg alpha helices hauv myoglobin?
The 8 Alpha-Helices (A-H) of Myoglobin . Puas myoglobin muaj alpha helices? Myoglobin (thiab hemoglobin) yog qhov txawv ntawm qhov lawv muaj tsuas yog alpha helix theem nrab qauv(pom ntawm no ua helical loops hauv liab) txuas ua ke los ntawm stretches ntawm random coil .
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
Vim li cas alpha helices thiaj raug?
13.4. Cov qauv alpha helix ua kom zoo dua ntawm hydrogen daim ntawv cog lus ntawm CO thiab NH pawg ntawm cov saw tseem ceeb kom ruaj khovCov pab pawg CO ntawm txhua cov amino acid tsim ib daim ntawv cog lus hydrogen nrog NH pawg amino acid plaub.
