| Definition | GE2270A is the model molecule of cyclic thiazolyl peptide elfamycins. GE2270A is produced by Planobispora rosea. Biosynthesis of the molecule has been shown to originate as a ribosomally synthesized peptide that undergoes significant post-translational modification. Clinical use of cyclic thiazolyl peptides is hindered by their low water solubility and bioavailability. |
