The Streptomycin molecule in 3-D

The Streptomycin molecule - rotatable in 3 dimensions

Streptomycin is an aminoglycoside antibiotic, found as a metabolic product of Streptomyces spp.

It is bactericidal in action, and was the first antibiotic used in the treatment of TB (tuberculosis), but it is no longer used for this purpose due to bacterial resistance.

It inhibits protein synthesis by combining irreversibly with one subunit of the bacterial ribosomes.

Streptomycin consists of three ring-shaped components - basically sugars with several amino groups - joined with standard glycosidic links:
