Abstract excerpt
We have identified the Schizosaccharomyces pombe SPBC3E7.06c gene (fnx2(+)) from a homology search with the fnx1(+) gene involving in G(0) arrest upon nitrogen starvation. Green fluorescent protein-fused Fnx1p and Fnx2p localized exclusively to the vacuolar membrane. Uptake of histidine or isoleucine by S. pombe cells was inhibited by concanamycin A, a specific inhibitor of the vacuolar H(+)-ATPase. Amino acid...
