Abstract
McConville et al. leverage CRISPR-Cas to demonstrate that mutations in crrB induce high-level polymyxin resistance in Klebsiella pneumoniae via the addition of L-Ara4N and pEtN to lipid A. CrrB mutations also increase virulence while conferring a fitness cost and alter carbon metabolism through activation of the pentose phosphate pathway.
