PEX genes encode proteins (peroxins) that are required for the biogenesis of peroxisomes. One of these peroxins, Pex5p, is the receptor for matrix proteins with a type 1 peroxisomal targeting signal(More)
We have cloned the Hansenula polymorpha PEX4 gene by functional complementation of a peroxisome-deficient mutant. The PEX4 translation product, Pex4p, is a member of the ubiquitin-conjugating enzyme(More)
PEX3 encodes at 52 kDa peroxisomal membrane protein (PMP), essential for peroxisome biogenesis in the yeast Hansenula polymorpha. The relation between Pex3p levels and peroxisome formation was(More)
Pex3p is a peroxisomal membrane protein that is essential for peroxisome biogenesis. Here, we show that a conserved stretch of positively charged amino acids (Arg(11)-X-Lys-Lys-Lys(15)) in the N(More)
