Qhov sib piv, feem ntau eukaryotic DNA ligases, ua ke nrog archaeal thiab bacteriophage enzymes, poob rau hauv tsev neeg thib ob; Cov enzymes no siv ATP ua cofactor.
Pob ligases xav tau ATP?
Ob DNA ligases feem ntau siv. … T4 ligase xav tau ATP thaum E. coli ligase xav tau NAD+ (Nicotinamide adenine dinucleotide yog coenzyme uas muaj 2 nt koom los ntawm lawv pawg phosphate.). Ob qho tib si catalyze kev koom tes ntawm 5'-phosphate thiab 3'-OH pawg los tsim ib daim ntawv cog lus phosphodiester.
Vim li cas ligases xav tau ATP?
Ob kauj ruam ntawm DNA ligation cov tshuaj tiv thaiv
Cov tshuaj tiv thaiv DNA ligation nws tus kheej muaj ob kauj ruam yooj yim. Ua ntej cov DNA kawg yuav tsum sib tsoo los ntawm lub sijhawm thiab nyob ua ke ntev txaus rau cov ligase koom nrog lawv. … Txhawm rau tso cai rau cov enzyme ua cov tshuaj tiv thaiv ntxiv rau AMP hauv qhov chaw ua haujlwm enzyme yuav tsum tau ntxiv los ntawm ATP.
Yuav ua li cas yog ligases?
DNA ligases ua lub luag haujlwm tseem ceeb hauv tuav txoj kev ncaj ncees ntawm genomic los ntawm kev koom nrog kev so hauv phosphodiester qaum ntawm DNA uas tshwm sim thaum rov ua dua thiab rov ua dua, thiab ua rau muaj txiaj ntsig ntawm DNA puas thiab nws kho. Peb tib neeg cov noob, LIG1, LIG3 thiab LIG4 encode ATP-dependent DNA ligases.
Dab tsi yog ligases lawv ua haujlwm nquag lossis ua ntu zus?
DNA ligase yog nquag thaum lub sijhawm rov ua dua, kho thiab rov ua dua txheej txheem ntawm DNA. Nws yog dav siv nyob rau hauv kev kho ntawm ib leeg-strandtawg nyob rau hauv duplex DNA ntawm cov kab mob nyob uas siv lub complementary strand ntawm ob helix raws li ib tug template, thaum ib co ntaub ntawv tej zaum tshwj xeeb kho ob-strand puas.

Puas siv cov xim yooj yim siv decolorizer?
Zoo siab txais tos rau Microbugz - Yooj Yim Stains. Qhov yooj yim stain tuaj yeem siv los txiav txim siab ntawm tes, qhov loj me, thiab kev teeb tsa. Muaj tseeb rau nws lub npe, qhov yooj yim stain yog ib qho yooj yim staining txheej txheem nrog tsuas yog ib qho stain.
Excel puas tuaj yeem siv ntau tus neeg siv?
Yog tias koj xav kom ntau tus neeg siv ua haujlwm hauv tib phau ntawv ua haujlwm Excel ib txhij, koj tuaj yeem khaws phau ntawv ua haujlwm ua phau ntawv qhia ua haujlwm. Cov neeg siv tuaj yeem nkag mus rau cov ntaub ntawv, ntxig kab thiab kab, ntxiv thiab hloov cov qauv, thiab hloov formatting.
Puas yog kev siv hluav taws xob siv hluav taws xob?
Usability engineering yog kev qhuab qhia uas tsom mus rau kev txhim kho kev siv tau ntawm kev sib tham sib. Nws rub tawm cov kev xav los ntawm kev tshawb fawb hauv computer thiab kev puas siab puas ntsws los txhais cov teeb meem uas tshwm sim thaum siv cov kab ke.
Puas siv hluav taws xob hauv qhov hluav taws xob tuaj yeem siv rau ntawm qhov loj?
Txawm hais tias tsawg dua, lwm hom kev siv hluav taws xob hauv av tuaj yeem siv los muab ntau lub zog ntau dua. Tapping qhov chaw ntawm cov dej kub faus rau hauv qab lub ntiaj teb saum npoo tuaj yeem muab cua sov rau cov neeg coob coob, thiab tsim kom muaj zog txaus los tsim hluav taws xob loj.
Pob myosin siv atp?
Qhov kev txav ntawm cov leeg nqaij luv tshwm sim thaum myosin taub hau khi rau actin thiab rub cov actin sab hauv. Qhov kev txiav txim no xav tau zog, uas yog muab los ntawm ATP. Myosin khi rau actin ntawm qhov chaw khi ntawm globular actin protein.
