• Molecule Alteration: Expression; Inherence
• Resistant Disease: Streptomyces ambbyaciens infection [ICD-11: 1C43.0]
• Experimental Note: Discovered Using In-vivo Testing Model
• In Vitro Model: Escherichia coli; 668369

• In Vitro Model: Streptomyces lividans strain OS456; 1916
• Experiment for Molecule Alteration: DNA sequencing assay
• Experiment for Drug Resistance: Observation of growth inhibition zones assay
• Mechanism Description: With UDP-[14C]glucose as the cofactor, crude S30 extracts from OS456(pOS41.90) were tested on various macrolides. Among those, chalcomycin was the most active substrate. Methymycin, tylosin, pikromycin, and rosaramicin were four of the best substrates. Oleandomycin, josamycin, and carbomycin were glycosylated to a lesser extent. Macrolides that were found to be as poor substrates of GimA as lankamycin were erythromycin and angolamycin. Spiramycin was also a very poor substrate.
