Heterologous complementation of peroxisome function in yeast: the Saccharomyces cerevisiae PAS3 gene restores peroxisome biogenesis in a Hansenula polymorpha per9 disruption mutant.
PER genes are essential for the biogenesis of peroxisomes in the yeast Hansenula polymorpha. Here we describe the functional complementation of a H. polymorpha per9 disruption strain (delta per9) by a heterologous gene. The Saccharomyces cerevisiae Pas3p, a homologue of per9p, restored peroxisome biogenesis and peroxisomal protein import in the delta per9 mutant, allowing it to grow again on methanol as sole carbon and energy source. This result shows that heterologous complementation of peroxisome function in yeast is indeed feasible and furthermore suggests that H. polymorpha delta per9 may be the candidate of choice to attempt the isolation of Per9p homologues from higher eukaryotes by functional complementation.
