Albomycin is a naturally occurring antibiotic belonging to the class of sideromycins, which are "compounds composed of iron carriers called siderophores linked to antibiotic moieties", and is particularly effective against gram negative bacteria of the family Enterobacteriaceae and few gram positive bacteria like Streptococcus pneumoniae, Bacillus subtilis and Staphylococcus aureus. In 2000 a group of scientists from SmithKline Beecham Pharmaceuticals, UK reported that the antibiotic part of albomycin in vitro can inhibit seryl t-RNA synthetase from both eukaryotic and prokaryotic representatives.
