The functions of these enzymes are not fully understood. We disclose herein that SltB3 of P. aeruginosa is an exolytic lytic transglycosylase. We characterize its reaction and its products by the use of peptidoglycan-based molecules. The enzyme recognizes a minimum of four sugars in its substrate but can process a substrate comprised of a peptidoglycan of 20 sugars. The ultimate product of the reaction is N-acetylglucosamine-1,6-anhydro-N-acetylmuramic acid. The X-ray structure of this enzyme is reported for the first time. The enzyme is comprised of four domains, arranged within an annular conformation. The polymeric linear peptidoglycan substrate threads through the opening of the annulus, as it experiences turnover.
