The first genome sequences of the important yeast protein production host Pichia pastoris have been released into the public domain this spring. In order to provide the scientific community easy and versatile access to the sequence, two web-sites have been installed as a resource for genomic sequence, gene and protein information for P. pastoris: A GBrowse based genome browser was set up at htt...

Phytase expressed and anchored on the cell surface of Pichia pastoris avoids the expensive and time-consuming steps of protein purification and separation. Furthermore, yeast cells with anchored phytase can be used as a whole-cell biocatalyst. In this study, the phytase gene of Citrobacter amalonaticus was fused with the Pichia pastoris glycosylphosphatidylinositol (GPI)-anchored glycoprotein h...

A gene encoding Rhizopus oryzae lipase containing prosequence (ProROL) was cloned into the pPICZαA and electrotransformed into the Pichia pastoris X-33 strain. The lipase was functionally expressed and secreted in Pichia pastoris with a molecular weight of 35 kDa. The maximum lipase activity of recombinant lipase (rProROL) was 21,000 U/mL, which was obtained in a fed-batch cultivation after 168...

The thermal denaturation of the acid proteinase from Aspergillus saitoi was studied by CD and differential scanning calorimetry (DSC). This process seemed to be completely irreversible, as protein samples that were heated to temperatures at which the transition had been completed and then cooled at 25 degrees C did not show any reversal of the change in the CD signal. Similar results were obtai...

The performance of the Etest for posaconazole (SCH 56592) susceptibility testing of 314 isolates of Candida spp. was assessed against the National Committee for Clinical Laboratory Standards (NCCLS) microdilution broth method. The NCCLS method employed RPMI 1640 broth medium, and MICs were read after incubation for 48 h at 35 degrees C. MICs were determined by Etest for all 314 isolates with RP...

Mitochondrial (mt) nucleoids were isolated with a high degree of purity from the yeast Pichia judinii, in which the mitochondrial DNA (mtDNA) is linear. Field-inversion gel electrophoresis (FIGE) reyealed that significant amounts of mtDNA could be isolated intact, as linear molecules of 41 kbp, from the isolated mt-nucleoids. Fifteen different proteins were detected in the mt-nucleoid fraction ...

lipases are versatile biocatalysts with a wide range of application in food, dairy, leather, paper, pharmaceutical and detergent industries.  in this study, mesophilic lipase gene from an indigenous bacillus pumilus f3 that already its gene had been sequenced and  identified, was cloned and expressed in methylotrophic yeast pichia pastoris and codon translation of lipase gene was evaluated in p...
