(unranked): Tus kab mob
Ib yam li ntawd, muaj pes tsawg enzymes muaj tus kab mob HIV?
Lub retroviral RNA genome encodes rau peb cov enzymes qhov tseem ceeb rau kab mob vais lav replication: (i) lub kis protease (PR), uas hloov cov virion tsis paub qab hau rau hauv kev paub tab kab mob vais lav los ntawm kev tshem tawm ntawm cov txheej txheem ua ntej polypeptides; (ii) thim rov qab transcriptase (RT), lub luag haujlwm rau kev hloov pauv ntawm ib leeg-tso tseg genomic RNA
Ib qho ntxiv, tus kab mob HIV sib thooj li cas? Thaum twg HIV kis tau tus kab mob ntawm tes, nws xub txuas rau thiab fuses nrog tus tswv tsev. Tom qab ntawd kis RNA hloov pauv mus rau hauv DNA thiab kab mob vais lav siv tus tswv cell lub tshuab rau rov ua dua nws tus kheej thaum txheej txheem hu ua thim rov qab. Cov ntawv luam tshiab ntawm HIV tom qab ntawd tawm ntawm tus tswv tsev cell thiab txav mus kis rau lwm lub cell.
Ua li no, dab tsi yog qee qhov tseem ceeb ntawm cov kab mob enzymes xav tau rau HIV lub neej voj voog?
HIV Protease HIV -1 protease ( HIV PR) yog aspartic protease uas yog tseem ceeb rau cov lub neej - lub voj voog ntawm HIV , tus kab mob retrovirus uas ua rau AIDS. HIV PR cleaves tshiab synthesized polyproteins ntawm qhov chaw tsim nyog los tsim kom muaj cov protein ntau ntawm cov kab mob sib kis. HIV virion ua.
Tus kab mob HIV kab mob lub neej yog dab tsi?
Lub neej voj voog . Cov kauj ruam uas HIV raws li kev sib npaug hauv lub cev. Cov txheej txheem pib thaum twg HIV ntsib CD4 cell. Xya kauj ruam hauv HIV lub neej voj voog yog: 1) khi; 2) fusion; 3) thim rov qab transcription; 4) kev sib koom ua ke; 5) rov ua dua ; 6) sib dhos; thiab 7) txiv hmab txiv ntoo.

Cov tshuaj aspirin muaj txiaj ntsig dab tsi rau cov enzymes?
Tshuaj aspirin thiab lwm yam tshuaj tsis-steroidal anti-inflammatory tshuaj (NSAIDs), xws li ibuprofen thiab indomethacin, ua haujlwm los ntawm inhibiting ib qho enzyme uas ua rau prostaglandins-hormone-like messenger molecules uas ua rau cov txheej txheem hauv lub cev, suav nrog o
Dab tsi yog siv tus xuav rau hauv cov khoom siv thaum muaj xwm ceev?
Emergency Essentials Emergency Whistle yog ib qho tseem ceeb ntxiv rau cov khoom siv thaum muaj xwm ceev, cov khoom siv mus pw hav zoov, thiab cov cuab yeej taug kev. Siv nws los pab cawm neeg pom koj, lossis nrhiav koj pab pawg thaum taug kev lossis mus pw hav zoov. Koj yeej tsis paub thaum twg koj yuav xav tau lub suab nrov nrov thaum muaj xwm txheej ceev
Cov kab mob dab tsi tshwm sim los ntawm cov enzymes?
Piv txwv li: Tsev neeg hypercholesterolemia. Kab mob Gaucher. Hunter syndrome. Kab mob kab mob. Maple syrup tso zis kab mob. Metachromatic leukodystrophy. Mitochondrial encephalopathy, lactic acidosis, mob stroke zoo li lub sijhawm (MELAS) Niemann-Pick
Vim li cas cov neeg mob cystic fibrosis siv cov enzymes?
Hauv cystic fibrosis (CF), cov ducts hauv lub lauj kaub tais diav tau txhaws nrog cov tuab, nplaum nplaum. Cov hnoos qeev no thaiv cov enzymes los ntawm kev nkag mus rau cov zaub mov hauv cov hnyuv. Hmoov zoo, pancreatic enzyme hloov pauv lossis "enzymes" muaj los pab cov neeg nrog CF zom thiab nqus lawv cov zaub mov
Cov enzymes ua dab tsi hauv cov hnyuv?
Kev zom zaub mov hauv cov hnyuv me tau txuas ntxiv los ntawm cov txiav ua kua pancreatic, suav nrog chymotrypsin thiab trypsin, txhua tus uas ua raws cov kev sib txuas tshwj xeeb hauv cov amino acid sib txuas. Nyob rau tib lub sijhawm, cov hlwb ntawm txhuam ciam teb zais cov enzymes xws li aminopeptidase thiab dipeptidase, uas txuas ntxiv ua rau peptide chains
