Scientists ‘unmask’ superbug-shielding protein .

Post Date : 16/02/2017

Scientists from University of Western Australia have successfully mapped three-dimensional molecular structure of EptA protein that shields superbugs from antibiotics. The EptA protein causes multi-drug resistance by masking bacteria from both the human immune system and important antibiotics.The shape of protein was mapped using technique called X-ray crystallography which is mainly used for determining the atomic and molecular structure of a crystal. The protein, EptA, allows some strains to shrug off colistin, a last antibiotic available in the world for treating infections when all other antibiotics fail. Significance: This mapping is a breakthrough because it will allow development of a drug to prevent superbugs hiding from medication. Thus, it open door to combating the threat of antibiotic resistance and is considered as a huge step forward in the global fight against superbugs.
