Abstract

Two nucleoside transport systems have been verified and separated by mating and recombination experiments. The recipient strain was a mutant which is negative for transport of all nucleosides. The two systems differ in specificity and in regulation. One system transports pyrimidine and adenine nucleosides. It is regulated by the cytR gene. The other system transports all nucleosides and is regulated by the cytR as well as by the deoR genes. Enzyme assays performed on whole cells of strains, able or unable to transport nucleosides, indicate that the nucleoside catabolizing enzymes are located inside the permeability barrier of the cell.
