A genomic sequence of the Schizosaccharomyces pombe 16 kDa vacuolar H⁺‐ATPase

We have isolated the gene encoding the 16 kDa vacuolar H(+)-ATPase from Schizosaccharomyces pombe. On the basis of RNA splicing signals and amino acid sequence homology with other 16 kDa H(+)-ATPases, the genomic DNA sequence indicated the 16 kDa protein is encoded by five exons. The C-terminal 50 amino acids has more than 90% homology with vacuolar H(+)-ATPases of mammalian cells.
