Transport of nucleosides in Bacillus subtilis: characteristics of cytidine-uptake

Abstract

In Bacillus subtilis SMYW cytidine and uridine are transported by a common system. Transport of these substances requires metabolic energy. After 60 sec of 3II-cytidine-uptake practically all accumulated radioactivity was found in phosphorylated products. Addition of ribonucleosides with inhibitory effect upon cytidine-uptake resulted in competitive type of inhibition while interference with deoxyribonucleosides was of hyperbolic competitive type. Adenosine possesses a high affinity to cytidine-transporting site but requires different system(s) for its own transport. Guanosine, adenine, cytosine and 5-nucleotides do not interfere with cytidine-uptake.
