General Information

General Information Comment Organism
evolution WarA and WarB have structural similarities with the bi-functional Escherichia coli LPS O antigen regulator WbdD. A predicted three-dimensional model is generated with a very high confidence on the Escherichia coli serotype O9a WbdD protein (19% sequence identity, 69% sequence coverage, 100% confidence) Pseudomonas aeruginosa
malfunction The immune response to Pseudomonas aeruginosa in a Pseudomonas-zebrafish hindbrain infection model shows that deletion of warA or sadC does not reduce bacterial load. A phenotype of significantly increased neutrophil recruitment is observed for a warA deletion mutant. Infection with a warA mutant also induces TNF-alpha mRNA levels significantly higher than wild-type infected larvae Pseudomonas aeruginosa
additional information WarA is a methyltransferase in complex with a putative kinase WarB. WarA binds to cyclic-di-GMP, which potentiates its methyltransferase activity. Bacterial two-hybrid assay Pseudomonas aeruginosa
physiological function WarA influences Pseudomonas aeruginosa O antigen modal distribution and interacts with the LPS biogenesis machinery. LPS is known to modulate the immune response in the host, WarA is involved in the ability of Pseudomonas aeruginosa to evade detection by the host. Cyclic-di-GMP regulates lipopolysaccharide modification and contributes to Pseudomonas aeruginosa immune evasion. WarA might play a similar functional role as WbdD in regulating chain length and termination of LPS O antigen synthesis. The immune response to Pseudomonas aeruginosa in a Pseudomonas-zebrafish hindbrain infection model shows that deletion of warA or sadC does not reduce bacterial load. The regulation of LPS by SadC and WarA plays a critical role in immune cell evasion during infection Pseudomonas aeruginosa
