Hygromycin B is an aminocyclitol antibiotic that strongly inhibits both 70S and 80S ribosomes, produced by streptomyces hygroscopicus. Hygromycin B inhibits protein synthesis in archaebacteria, eubacteria, fungi, and higher eukaryotes[3]. in vitro，hygromycin B at 0.38 mM concentration completely halts yeast cell growth in rich media, presumably by preventing protein synthesis by cytoplasmic ribosomes[4]. in vivo，hygromycin B inhibits protein synthesis by blocking ribosomal translocation without causing significant misreading[3]. In eukaryotes, the antibiotic affects EF-2-mediated translocation of A site bound tRNA to the P site. The inhibition of translocation is accompanied by an increase in the affinity of the A site for aminoacyl-tRNA[5].
