title: Transport of basic aminoacids in E. coli.
abstract: 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.
