Ribonuclease A Ribonuclease A Bovine pancreatic ribonuclease, kuj feem ntau hu ua bovine pancreatic ribonuclease A lossis yooj yim RNase A, yog pancreatic ribonuclease enzyme uas cleaves ib leeg-stranded RNAatic Bovine ribonuclease yog ib qho ntawm cov qauv qauv ntawm cov protein science. https://en.wikipedia.org › Bovine_pancreatic_ribonuclease
Bovine pancreatic ribonuclease - Wikipedia
yog lub plab zom mov secreted los ntawm pancreas uas tshwj xeeb "digests" lossis hydrolyzes RNA (tab sis tsis yog DNA) polymers los ntawm endonuclease cleavage ntawm phosphodiester bonds tsim cov kev sib txuas ntawm cov nyob ib sab. ribonucleotide residues nyob rau hauv cov molecules.
Vim li cas hlwb thiaj muaj ribonuclease?
Ribonucleases (RNases) ua si lub luag haujlwm tseem ceeb hauv txhua yam ntawm RNA metabolism, tab sis lawv kuj tuaj yeem ua rau cov enzymes puas tsuaj uas yuav tsum tau tswj kom tsis txhob plam kev puas tsuaj ntawm RNA molecules.. Raws li qhov tshwm sim, cov hlwb tau hloov kho ntau lub tswv yim los tiv thaiv RNAs tawm tsam RNase kev ua.
RNase nyob qhov twg?
RNA ib feem ntawm RNase P yog pom nyob rau hauv cov cytosolic feem ntawm cov hlwb overexpressing no RNA, thaum lub overexpressed RNase P protein sediments nrog cov membrane feem; qhov no qhia tias RNase P protein anchors RNA catalytic moiety ntawm enzyme mus rau ib qho chaw loj.
Thaum twg ribonuclease A nrhiav tau?
Pancreatic ribonuclease tau piav qhia thawj zaug hauv 1920 los ntawm American biochemist W alter Jones (1865-1935), uas qhia tias nws tuaj yeem zom cov poov xab RNA. Nws tau raug ntxuav ib nrab xyoo 1938 los ntawm American microbiologist René Jules Dubos (1901-1982) thiab cais tawm hauv crystalline daim ntawv ob xyoos tom qab los ntawm M. Kunitz.
Dab tsi yog txoj haujlwm ntawm Ribonucleases?
Ribonucleases (RNases) yog cov neeg tseem ceeb ntawm kev tiv thaiv tus tswv tsev thiab pab tswj cov ntaub so ntswg homeostasis thiab lub cev tsis muaj dej. Secreted raws li ib tug ntau haiv neeg ntawm cellular raug mob, lawv kho cov txheej txheem signaling, thiab tau muab faib ua alarmins (1).

Ntawm qhov chaw twg tsis pom los ntawm qhov pom sab hauv?
Lub qhov ntswg zoo tshaj plawsyog nyob tom qab thiab yog li tsis pom nyob rau sab xub ntiag. Cov duab 9.1, 9.3, 9.5, 9.7, thiab 9.10 N/A Pab txhawb rau anterior cranial fossa; tsim ib feem ntawm qhov ntswg septum thiab qhov ntswg kab noj hniav;
Nyob rau qhov chaw nyob ze rau qhov pom?
Kev nyob ze ze Lub zeem muag Qhov kev pab cuam reflex (lossis nyob ze teb) yog peb feem reflexuas coj cov khoom ze rau hauv kev tsom los ntawm lens thickening, pupillary constriction, thiab sab hauv kev sib hloov ntawm qhov muag-qhov muag convergence.
Qhov qhov muag tsis pom ntawm lub tsheb thauj khoom nyob qhov twg?
Tsev tsheb ciav hlau qhov muag tsis pom muaj xws li: Ncaj nraim rau pem hauv ntej ntawm lub tsheb thauj khoom mus txog 20 ko taw Ncaj nraim hauv qab lub tsheb thauj khoom li 30 ko taw Txhua sab ntawm lub tsheb thauj mus rau sab nraub qaum Tam sim ntawd hauv qab thiab qab tus neeg tsav tsheb qhov rais Puas muaj qhov muag tsis pom kev tsheb thauj mus los?
Qhov kev pom twg pom kev tsis sib haum xeeb yog qhov tsim nyog?
Thaum tib neeg kev sib raug zoo pom tau txais kev sib haum xeeb ntawm lub koom haum ua ib feem tseem ceeb, kev sib cuam tshuam kev pom ntawm-kev tsis sib haum xeeb ntawm lub koom haum yuav siv tib lub tswv yim ib kauj ruam ntxiv. Nws qhia tias qhov kev tsis sib haum xeeb tsis tu ncua, tsawg kawg yog qhov tsim nyog thiab muaj txiaj ntsig zoo rau ib pab pawg .
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?
