Protein
Purine-cytosine permease fcyB
Organism
Emericella nidulans (strain FGSC A4 / ATCC 38163 / CBS 112.46 / NRRL 194 / M139)
Function
This permease has a broad specificity towards purines, and also transports cytosine, but neither uracil nor thymine. Contributes very little in purine uptake. Its major role may be the uptake of cytosine.
Similarity
Belongs to the purine-cytosine permease (2.A.39) family.
