An ABC‐type, high‐affinity urea permease identified in cyanobacteria

Summary Urea is an important nitrogen source for many microorganisms, but urea active transporters have not been characterized at a molecular level in any bacterium. Cells of Synechocystis sp. PCC 6803 and Anabaena sp. PCC 7120 exhibited the capacity to take up [14C]‐urea from low‐concentration (...
