Streptomycin yog aminoglycoside tshuaj tua kab mob ua los ntawm cov av actinomycete Streptomyces griseus. Nws ua los ntawm kev khi rau 30S ribosomal subunit ntawm cov kab mob uas raug cuam tshuam thiab cuam tshuam qhov pib thiab elongation cov kauj ruam hauv cov protein synthesis. Nws yog bactericidal vim cov teebmeem uas tsis nkag siab tag nrho.
Ib sab ntawm qhov no, hom kev txiav txim rau streptomycin yog dab tsi?
Mechanism ntawm kev txiav txim Streptomycin yog ib qho protein synthesis inhibitor. Nws khi rau 16S rRNA me me ntawm 30S subunit ntawm cov kab mob ribosome, cuam tshuam nrog kev khi ntawm formyl-methionyl-tRNA rau 30S subunit.
Tsis tas li ntawd, vim li cas streptomycin thiaj li zoo? Streptomycin , tshuaj tua kab mob synthesized los ntawm cov av kab mob Streptomyces griseus. Vim nws yog zoo tawm tsam ntau yam kab mob, streptomycin tau siv ntau zaus, nrog rau qhov tshwm sim uas muaj ntau yam kab mob pib rhiab heev, nrog rau cov kab mob uas ua rau tuberculosis, ua rau cov tshuaj tiv thaiv kab mob.
Ua li no, streptomycin ua haujlwm tiv thaiv kab mob li cas?
Streptomycin nres kab mob kev loj hlob los ntawm kev puas cell membranes thiab inhibiting protein synthesis. Tshwj xeeb, nws khi rau 16S rRNA ntawm tus kab mob ribosome, cuam tshuam nrog kev khi ntawm formyl-methionyl-tRNA rau 30S subunit. Qhov no tiv thaiv kev pib ntawm cov protein synthesis.
Cov kab mob dab tsi tsim streptomycin?
Streptomyces griseus
