Sequence of ptb1, a gene for the beta subunit of the type-II geranylgeranyltransferase from the fission yeast Schizosaccharomyces pombe.
We have isolated and sequenced the ptb1 gene from the fission yeast Schizosaccharomyces pombe. Sequence analysis suggests that Ptb1 is the beta subunit of the type-II geranylgeranyltransferase that is responsible for geranylgeranylation of the Rab-like YPT proteins in this yeast.
