Streptomycin is a protein synthesis inhibitor. It binds to the S12 Protein of the 30S subunit of the bacterial ribosome, interfering with the binding of formyl-methionyl-tRNA to the 30S subunit. This prevents initiation of protein synthesis and leads to death of microbial cells. Humans have structurally different ribosomes from bacteria, thereby allowing the selectivity of this antibiotic for bacteria. However at low concentrations Streptomycin only inhibits growth of the bacteria by inducing prokaryotic ribosomes to misread mRNA. It is an antibiotic that inhibits both Gram-positive and Gram-negative bacteria and is a therefore a useful broad spectrum antibiotic
What else can I help you with?
Does streptomycin kill gram negative bacteria?
Yes, streptomycin is effective against both gram positive and gram negative bacteria. It works by inhibiting protein synthesis in bacterial cells, leading to their death.
Is streptomycin a bad bacteria?
Streptomycin is not a bacteria; it is an antibiotic derived from the bacterium Streptomyces griseus. Streptomycin is used to treat bacterial infections, particularly tuberculosis and certain types of bacterial meningitis.
Is streptomycin bacteriostatic or bacteriocidal?
it is bactericidal b/c it binds 30s ribosomal subunit &inhibit protein synthesis
Do bacteriostatic agents kill bacterial cells?
No, bacteriostatic agents inhibit the growth and reproduction of bacterial cells but do not directly kill them. These agents usually work by targeting specific cellular processes or structures needed for bacterial growth.
What antibiotics are made with streptomyces griseus?
S. griseus produces antibiotic, streptomycin, and it is useful against gram negative bacteria. Streptomycin and its relatives are considered reserve antibiotics for resistant bacterial strands because they can be neurotoxic and nephrotoxic.
Why bacterial cell are sensitive to streptomycin and chloramphenicol antibiotic?
Bacterial cells are sensitive to streptomycin because it targets the bacterial ribosomes, interfering with protein synthesis. Chloramphenicol, on the other hand, inhibits protein synthesis by binding to the bacterial ribosomes and preventing the aminoacyl-tRNA from reaching the ribosome. These antibiotics disrupt essential bacterial processes, leading to cell death.
Does streptomycin kill gram negative bacteria?
Yes, streptomycin is effective against both gram positive and gram negative bacteria. It works by inhibiting protein synthesis in bacterial cells, leading to their death.
Is streptomycin a bad bacteria?
Streptomycin is not a bacteria; it is an antibiotic derived from the bacterium Streptomyces griseus. Streptomycin is used to treat bacterial infections, particularly tuberculosis and certain types of bacterial meningitis.
How can you kill bacterial cells by centrifugation?
Bacterial cells cannot be lysed (or killed) through centrifugation alone. Although repeated centrifugation and resuspending will kill many bacterial cells as a result of shear stress on the cell membrane
Is streptomycin bacteriostatic or bacteriocidal?
it is bactericidal b/c it binds 30s ribosomal subunit &inhibit protein synthesis
Do bacteriostatic agents kill bacterial cells?
No, bacteriostatic agents inhibit the growth and reproduction of bacterial cells but do not directly kill them. These agents usually work by targeting specific cellular processes or structures needed for bacterial growth.
Why does streptomycin kill the bacteria and not us?
Streptomycin binds to bacterial 30S ribosomal subunit and inhibits protein production by the bacteria. Human beings are are not affected because our ribosomes have a 40S subunit and a 60S subunit, no 30S subunit.
What antibiotics are made with streptomyces griseus?
S. griseus produces antibiotic, streptomycin, and it is useful against gram negative bacteria. Streptomycin and its relatives are considered reserve antibiotics for resistant bacterial strands because they can be neurotoxic and nephrotoxic.
Is streptomycin an example of an antibiotic?
Yes, streptomycin is an antibiotic that is commonly used to treat bacterial infections such as tuberculosis. It belongs to a class of antibiotics known as aminoglycosides.
What molds produce substances that kill bacteria?
Penicillium and Streptomyces molds produce substances known as penicillin and streptomycin, respectively, which are able to kill bacteria. These substances are used as antibiotics to treat bacterial infections in humans and animals.
What are the compounds that kill bacterial cells without harming the cells of humans?
They are called antibiotics (meaning against life) and generally interfere in only a few specific chemical reactions, those found in bacterial cells but not human cells.
The antibiotic streptomycin prevents protein synthesis in prokaryotes Which cell component is the most likely target of this antibiotic?
The ribosomes are the most likely target of streptomycin in prokaryotes. Streptomycin interferes with the function of the bacterial ribosome, specifically the 30S subunit, disrupting protein synthesis and leading to cell death.
