Pyoverdine I (PVDI) is the major siderophore produced by Pseudomonas aeruginosa PAO1 to import iron. Its biosynthesis requires the coordinated action of cytoplasmic, periplasmic and membrane proteins. The individual enzymatic activities of these proteins are well known. However, their subcellular distribution in particular areas of the cytoplasm, periplasm,(More)
Pseudomonas aeruginosa produces the siderophore, pyoverdine (PVD), to obtain iron. Siderophore pathways involve complex mechanisms, and the machineries responsible for biosynthesis, secretion and uptake of the ferri-siderophore span both membranes of Gram-negative bacteria. Most proteins involved in the PVD pathway have been identified and characterized but(More)
Bacillus subtilis c-di-AMP synthase DisA and RecA-related RadA/Sms are involved in the repair of DNA damage in exponentially growing cells. We provide genetic evidence that DisA or RadA/Sms is epistatic to the branch migration translocase (BMT) RecG and the Holliday junction (HJ) resolvase RecU in response to DNA damage. We provide genetic evidence damage.(More)
