Scientists produce new antibiotics by gene editing
Scientists have discovered a new route to produce complex antibiotics exploiting gene editing to re-programme pathways to future medicines urgently required to combat antimicrobial resistance , treat neglected diseases and tackle future pandemics. Researchers from The University of Manchester have discovered a new way of manipulating key assembly line enzymes in bacteria which could pave the way for a new generation of antibiotic treatments. New research published today , describes how CRISPR-Cas9 gene editing can be used to create new nonribosomal peptide synthetase (NRPS) enzymes that deliver clinically important antibiotics. NRPS enzymes are prolific producers of natural antibiotics such as penicillin. However, up until now, manipulating these complex enzymes to produce new and more effective antibiotics has been a major challenge. The UK government suggest antimicrobial resistance ( AMR ) infections are estimated to cause 700,000 deaths each year globally and are predicted to rise to 10 million, costing the global economy $100 trillion, by 2050. AMR also threatens many of the UN's Sustainable Development Goals (SDGs), with an extra 28 million people that could be forced into extreme poverty by 2050 unless AMR is contained.
