ORN mutant, shows growth defect, YtqI from Bacillus subtilis is able to complement the mutant
additional information
construction of an enzyme knockout mutant by gene replacement, Pseudomonas aeruginosa DELTAorn mutant has high intracellular cyclic diguanylate (c-di-GMP) levels, causing this strain to overexpress extracellular polymers and overproduce biofilm. Mutant DELTAorn cells possess highly elevated 5'-phosphoguanylyl-(3',5')-guanosine (pGpG) levels

additional information
generation of enzyme mutant DELTAorn, mRNA levels of pyocin biosynthesis genes in the DELTAorn mutant compared to those in wild-type strain PA14. Mutation of orn drastically increases bacterial susceptibility to quinolones but not to tetracycline, aminoglycoside, or beta-lactam antibiotics. Upregulation of pyocin genes contributes to increased susceptibility to ciprofloxacin in the orn mutant. PrtR stability is reduced by the mutation of orn

additional information
generation of enzyme mutant DELTAorn. The lysates from DELTAorn show 25fold decrease in 5'-phosphoguanylyl-(3',5')-guanosine (pGpG) hydrolysis. Complementation with wild-type, but not active site mutants, restores hydrolysis. Accumulation of pGpG in the DELTAorn strain inhibits PDE-As, increasing cyclic-diguanylate (c-di-GMP) concentration. Increased transcription from the cyclic-diguanylate-regulated pel promoter is observed. Additionally, the cyclic-diguanylate-governed auto-aggregation and biofilm phenotypes are elevated in the DELTAorn strain in a pel-dependent manner. Detection of elevated levels of pGpG and cyclic-diguanylate in the DELTAorn strain

oligoribonuclease null mutant J3411 (DELTAornA::apr), reveals a conditional defect in morphological differentiation that is reminiscent of bldA. PpJS93, containing ornA under the control of a constitutive promoter, completely suppresses the phenotype of Streptomyces coelicolor J3411 (DELTAornA::apr), but pJS94 (encoding catalytically inactive OrnA D130A) does not
