Cluster 1 397-400 amino acids (not heteromeric)

b2393 nucleoside:H+ symporter NupC from Escherichia coli K-12 substr. MG1655
NUPC_ECOLI / P0AFF2 Nucleoside permease NupC; Nucleoside-transport system protein NupC from Escherichia coli (strain K12)
TC 2.A.41.1.1 / P0AFF2 Pyrimidine nucleoside:H+ symporter, NupC (Craig et al. 1994; Patching et al. 2005). Wild-type NupC had an apparent affinity for uridine of 22.2 +/- 3.7 muM and an apparent binding affinity of 1.8-2.6 mM, and various mutants with alterred properties were isolated and characterized (Sun et al. 2017). ADP-glucose is also a substrate of this system from Escherichia coli
