Methanol oxidation and assimilation in Hansenula polymorpha
The metabolism of methanol was monitored in whole cells of the methylotrophic yeast Hansenula polymorpha by using [13C]methanol and n.m.r. in vivo. The main products observed under normal conditions were trehalose and glycerol, whereas cells that were starved before exposure to [13C]methanol also accumulated glutamate, glutamine and alanine; formate was also more prominent in spectra from starv...
متن کاملBiosynthesis 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 کاملThe peroxisomal membrane protein Pex14p of Hansenula polymorpha is phosphorylated in vivo.
Hansenula polymorpha Pex14p (HpPex14p) is a component of the peroxisomal membrane essential for peroxisome biogenesis. Here, we show that HpPex14p is phosphorylated in vivo. In wild-type H. polymorpha cells, grown in the presence of [32P]orthophosphate, the 32P label was incorporated into HpPex14p. Labelled HpPex14p was induced after a shift of cells to methanol-containing media and rapidly dis...
متن کاملHansenula polymorpha Pex19p is essential for the formation of functional peroxisomal membranes.
We have cloned and characterized the Hansenula polymorpha PEX19 gene. In cells of a pex19 disruption strain (Hppex19), induced on methanol, peroxisome structures were not detectable; peroxisomal matrix proteins accumulated in the cytosol, whereas peroxisomal membrane proteins (PMPs) were mislocalized to the cytosol (Pex3p) and mitochondria (Pex14p) or strongly reduced to undetectable levels (Pe...
متن کاملHansenula polymorpha Pex20p is an oligomer that binds the peroxisomal targeting signal 2 (PTS2).
We have cloned and characterized the Hansenula polymorpha PEX20 gene. The HpPEX20 gene encodes a protein of 309 amino acids (HpPex20p) with a calculated molecular mass of approximately 35 kDa. In cells of an HpPEX20 disruption strain, PTS2 proteins were mislocalized to the cytosol, whereas PTS1 matrix protein import proceeded normally. Also, the PTS2 proteins amine oxidase and thiolase were nor...
