2.A.57.1.7 The fluorouridine insensitive 1 (Fur1) or Ent3 pyrimidine nucleoside transporter (Traub et al., 2007). AtENT4, AtENT6 and AtENT7). Three paralogs, Ent4, Ent6 and Ent7, exhibited broad substrate specificity and transported the
purine nucleosides adenosine and guanosine, as well as the pyrimidine
nucleosides cytidine and uridine (Wormit et al. 2004). The apparent Km values were in the
range 3-94 μM, and transport was inhibited strongly by
deoxynucleosides, and to a smaller extent by nucleobases.
