Biosynthesis of peroxisomal enzymes in the methylotrophic yeast Hansenula polymorpha.
The dramatic expansion of the peroxisomal compartment known to occur in the methanol-utilizing yeast Hansenula polymorpha on transfer from glucose- to methanol-containing media was shown to be accompanied by the synthesis of at least six major polypeptides that dominate the polypeptide pattern of total cell extracts analyzed by NaDodSO(4)/polyacrylamide gel electrophoresis. Two of these polypep...
متن کاملExpression of recombinant staphylokinase in the methylotrophic yeast Hansenula polymorpha
BACKGROUND Currently, the two most commonly used fibrinolytic agents in thrombolytic therapy are recombinant tissue plasminogen activator (rt-PA) and streptokinase (SK). Whereas SK has the advantage of substantially lower costs when compared to other agents, it is less effective than either rt-PA or related variants, has significant allergenic potential, lacks fibrin selectivity and causes tran...
متن کاملThe methylotrophic yeast Hansenula polymorpha contains an inducible import pathway for peroxisomal matrix proteins with an N-terminal targeting signal (PTS2 proteins).
Two main types of peroxisomal targeting signals have been identified that reside either at the extreme C terminus (PTS1) or the N terminus (PTS2) of the protein. In the methylotrophic yeast Hansenula polymorpha the majority of peroxisomal matrix proteins are of the PTS1 type. Thus far, for H. polymorpha only amine oxidase (AMO) has been shown to contain a PTS2 type signal. In the present study ...
متن کاملChromosomal targeting of replicating plasmids in the yeast Hansenula polymorpha.
Using an optimized transformation protocol we have studied the possible interactions between transforming plasmid DNA and the Hansenula polymorpha genome. Plasmids consisting only of a pBR322 replicon, an antibiotic resistance marker for Escherichia coli and the Saccharomyces cerevisiae LEU2 gene were shown to replicate autonomously in the yeast at an approximate copy number of 6 (copies per ge...
متن کاملArchitecture of peroxisomal alcohol oxidase crystals from the methylotrophic yeast Hansenula polymorpha as deduced by electron microscopy.
The architecture of alcohol oxidase crystalloids occurring in vivo in the peroxisomes of methylotrophic yeasts was deduced from electron micrographs of similar crystals of the Hansenula polymorpha enzyme grown in vitro. Three characteristic views of the crystal are observed, as well as single layers in the very early stages of crystal formation. The crystal is concluded to be cubical, with ever...
