Streptomycin Sulfate is the sulfate salt form of streptomycin, an aminoglycoside antibiotic derived from Streptomyces griseus with antibacterial property. Streptomycin sulfate binds to the S12 protein of the bacterial 30S ribosomal subunit, thereby inhibiting peptide elongation and protein synthesis, consequently leading to bacterial cell death.
Mode of Action: Streptomycin acts by inhibiting prokaryote protein synthesis by binding to the S12 protein of the 30S ribosomal subunit, thus preventing the transition from imitation complex to chain-elongating ribosome. This causes miscoding or inhibits initiation.
Mode of Resistance: A mutation in rpsL, a gene for S12 ribosomal protein, prevents binding of streptomycin to the ribosome. An aminoglycoside phosphotransferase also inactivates streptomycin.
Antimicrobial spectrum: Streptomycin acts against gram-negative and gram-positive bacteria.
