Kanamycin B (CAS 4696-76-8)

Kanamycin B, also known as kanamycin sulfate B or bekkanamycin, is derived from the bacterium Streptomyces kanamyceticus. It is closely related to kanamycin A but features unique structural properties that are of significant interest in the field of biochemistry, particularly for studies focused on protein synthesis in bacterial systems. The primary action of kanamycin B involves binding to the 30S subunit of the bacterial ribosome. This interaction disrupts the normal process of protein synthesis by inducing the misreading of mRNA. As a result, incorrect amino acids are incorporated into polypeptides, leading to the production of malfunctioning proteins that can affect bacterial cell function. In research contexts, kanamycin B is utilized to explore the mechanics of ribosomal function and the specificity of molecule-to-ribosome interactions. It serves as a critical tool in studying how small changes in the molecular structure of compounds like kanamycin B can influence their interaction with ribosomal RNA and their overall impact on protein synthesis. This research helps to deepen the understanding of molecular biology and biochemistry, shedding light on fundamental cellular processes and the dynamics of ribosome activity. Such studies are essential for advancing our knowledge of cellular machinery and the biochemical pathways that underpin protein synthesis.
