The yicM gene of Escherichia coli was found by selection for resistance to 6-mercaptopurine. Translation and transcription initiation sites of yicM were determined. Overexpression of yicM increased resistance of sensitive cells to inosine and guanosine, decreased E. coli growth rate in medium containing these ribonucleosides as the sole carbon source, led to inosine accumulation by the E. coli strain deficient in purine nucleoside phosphorylase and enhanced the rate of inosine excretion by an inosine-producing strain. These results suggest that yicM encodes a purine ribonucleoside exporter and we have accordingly renamed it nepI (for 'nucleoside efflux permease-inosine'). << Less
