Cytosin permease
WebJul 9, 2010 · Moreover, several genes coding cytosine transporters have been identified in S. cerevisiae [28–30]. Given the close phylogenetic relationship between S. cerevisiae and C. glabrata, one may speculate that several genes coding cytosine permease analogs are also present in the C. glabrata genome.
