Cov tshuaj tua kab mob tuaj yeem cuam tshuam cov protein synthesis los ntawm kev tsom mus rau 30S subunit, piv txwv xws li spectinomycin, tetracycline, thiab aminoglycosides kanamycin thiab streptomycin, lossis mus rau 50S subunit, piv txwv xws li clindamycin, chloramphenicol linezolid, thiab macrolides erythromycin, Ua qhov no hauv kev xav, dab tsi inhibits protein synthesis?
Cov chav kawm tom ntej ntawm protein synthesis inhibitors yog aminoglycosides. Cov macrolides, xws li erythromycin, yog xav txog inhibit protein synthesis los ntawm kev khi rau 50S subunit thiab thaiv lub qhov uas cov hlua polypeptide yuav tsum tawm mus. Qhov no txhaws cov ribosome thiab nres kev txhais lus.
Ib yam li ntawd, dab tsi yog tshuaj tua kab mob inhibiting protein synthesis tham? Inhibition ntawm Protein Synthesis los ntawm Tshuaj tua kab mob . Lawv muaj peev xwm inhibiting protein synthesis nyob rau hauv ob qho tib si 70S thiab 80S (eukaryotic) ribosomes, tab sis lawv nyiam khi rau cov kab mob ribosomes vim qhov txawv ntawm cov qauv hauv RNA subunits.
Ib yam li ntawd, nws tau nug, cov tshuaj tua kab mob twg muaj feem cuam tshuam rau cov protein synthesis?
Cov tshuaj tua kab mob hauv qab no khi rau 30S subunit ntawm ribosome yog li inhibiting protein synthesis:
- Aminoglycoside tshuaj tua kab mob xws li:
- Neomycin sulfate.
- Amikacin.
- Gentamicin.
- Kanamycin sulfate.
- Spectinomycin.
- Streptomycin.
- Tobramycin.
Cov tshuaj tua kab mob dab tsi inhibit DNA synthesis?
Cov tshuaj hauv tsev neeg no, xws li nalidixic acid, ciprofloxacin ua , thiab norfloxacin , ua hauj lwm los ntawm inhibiting enzymes uas yuav tsum tau rau cov kab mob DNA synthesis. Yog li ntawd, nyob rau hauv sib piv rau lub rifamycin tshuaj , uas inhibit transcription ntawm DNA rau hauv RNA, lub quinolones thiab fluoroquinolones inhibit DNA replication.

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
Cov tshuaj twg ua los ntawm inhibiting protein synthesis ntawm cov kab mob?
Chloramphenicol. Chloramphenicol yog ib tug dav spectrum tshuaj tua kab mob uas ua raws li ib tug muaj zog inhibitor ntawm cov kab mob protein biosynthesis. Nws muaj keeb kwm kev kho mob ntev ntev tab sis cov kab mob tsis zoo yog tshwm sim
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
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Dab tsi yog cov tshuaj tua kab mob cuam tshuam nrog cov protein synthesis?
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 thaiv cov 50S polypeptide export qhov
