Erythromycin, macrolide, khi rau 23S rRNA tivthaiv ntawm 50S ribosome thiab cuam tshuam nrog kev sib dhos ntawm 50S subunits. Erythromycin, roxithromycin, thiab clarithromycin tag nrho tiv thaiv elongation ntawm cov kauj ruam transpeptidation ntawm synthesis los ntawm kev thaiv cov 50S polypeptide export qhov.
Tib neeg kuj nug, ua li cas cov tshuaj tua kab mob cuam tshuam rau protein synthesis?
Tag nrho cov tshuaj tua kab mob lub hom phiaj kab mob protein synthesis ua yog li los ntawm kev cuam tshuam nrog cov kab mob ribosome thiab inhibiting nws txoj haujlwm. Lub ribosome yuav tsis zoo li lub hom phiaj zoo rau kev xaiv toxicity, vim hais tias txhua lub hlwb, nrog rau peb tus kheej, siv ribosomes rau protein synthesis.
Ib yam li ntawd, cycloheximide inhibits protein synthesis li cas? Cycloheximide yog ib tug tshwm sim fungicide tsim los ntawm cov kab mob Streptomyces griseus. Cycloheximide exerts nws cov teebmeem los ntawm kev cuam tshuam nrog lub translocation kauj ruam nyob rau hauv protein synthesis (kev txav ntawm ob lub tRNA molecules thiab mRNA nyob rau hauv kev sib raug zoo rau ribosome), yog li thaiv eukaryotic translational elongation.
Ib yam li ntawd, dab tsi txwv cov protein synthesis?
Kev txiav txim ntawm protein synthesis tshwm sim ntawm ib qho teeb meem tshwj xeeb hauv mRNA. Cov txheej txheem polypeptide saw polymerization tso tseg thaum lub ribosome ncav cuag ib ntawm peb nres kos npe (codons) ntawm mRNA. The codons are UAA, UAG, and UGA.
Cov tshuaj tua kab mob twg tuaj yeem tiv thaiv kev tsim cov protein los ntawm kev tiv thaiv kab mob ribosomes los ntawm kev ua haujlwm?
Tetracyclines thiab Tigecycline (ib qho glycylcycline ntsig txog rau tetracyclines) thaiv lub A site ntawm lub ribosome , tiv thaiv Kev sib txuas ntawm aminoacyl tRNAs.

Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Dab tsi yog qhov cuam tshuam ntawm cov kab mob nroj tsuag uas rhuav tshem tag nrho cov chloroplasts hauv cov nroj tsuag?
Hauv cov xwm txheej ntxhov siab xws li drought thiab kub siab, cov nroj tsuag ntawm tes chloroplasts tuaj yeem ua rau puas tsuaj thiab tsim cov kab mob tsis zoo rau cov pa oxygen (ROS)
Vim li cas thiaj siv cov tshuaj tua kab mob hauv cov tshuaj distillation?
Lub hom phiaj ntawm kev sib tsoo granules Saib Lawv nres, uas qhov tshwm sim tam sim ntawd ntawm vapor npuas nyob rau hauv cov kua kub ua rau upwards splashing. Theanti-bumping granules ua raws li lub hom phiaj rau theformation ntawm vapor cia du boiling
Cov tshuaj tua kab mob dab tsi inhibits protein synthesis?
Cov tshuaj tua kab mob tuaj yeem tiv thaiv kev sib txuas ntawm cov protein los ntawm kev tsom mus rau 30S subunit, piv txwv xws li spectinomycin, tetracycline, thiab aminoglycosides kanamycin thiab streptomycin, lossis rau 50S subunit, piv txwv xws li clindamycin, chloramphenicol, linezolid, thiab thromycrolid
