Transport of basic aminoacids in E. coli.
Two transport systems for ornithine and one for arginine have been evidenced in E. coli KL16. The transport system for arginine is quite specific whereas the two for ornithine show a poor specificity. Citrulline and arginine non competitively inhibit ornithine transport. They show homotropic cooperativity and synergic inhibitory effect.
