2.A.57.2.1
Concentrative nucleoside (adenosine, uridine, cytosine, tubercidin):H+ symporter, NT1.1 (The Leishmania major orthologue, NT1.1 (Q4QF58), also transports tubercidin) (Stein et al., 2003). TMS 5 is an amphipathic helix that forms part of the nucleoside translocation pathway (Valdés et al. 2004). The intracellular and extracellular gates have been defined by modeling FucP (Valdés et al. 2012; Valdés et al. 2014).
