    Summary
    NupX (YeiJ) was reported to be a nucleoside transporter, and to be co-expressed with rihB (as indicated by polarity of an IS50 insertion upstream of rihB on nupX (yeiJ) expression, B. [More information is available at EcoGene: EG12029]. The YeiJ protein is an uncharacterized member of the NUP family of nucleoside transporters . [More information is available at EcoCyc: EG12029].
