Engineering small lantibiotics by use of novel enzymes and introducing additional modifications

Antibiotic resistance of human pathogens is on the rise, causing great threats to human health. Good surveillance and stewardship are needed, but not sufficient to tackle the problem. We will take lantibiotics and other modified peptides as scaffolds to design and produce novel antimicrobials with desired properties, including high activity against drug resistant pathogens such as Enterococcus faecalis, Klebsiella pneumoniae, Streptococcus pneumoniae. Selected molecules will be optimized for high stability, low rate of resistance development, good pharmacokinetic properties and low toxicity and histamine release. In the resistance development studies we will investigate the occurrence of persister and heteroresister cells, and determine the kinetics and the propensity of resistance development.
