Thiamine transport in Saccharomyces cerevisiae protoplasts.
Thiamine was found to be accumulated in protoplasts of Saccharomyces cerevisiae in the same manner as in intact cells, suggesting that a soluble thiamine-binding protein in periplasm may not be an essential component of the thiamine transport system of S. cerevisiae. It was also found that thiamine pyrophosphate cannot be taken up by yeast protoplasts.
متن کاملLiposome-mediated delivery of tobacco mosaic virus RNA into tobacco protoplasts: A sensitive assay for monitoring liposome-protoplast interactions.
Tobacco mosaic virus (TMV) RNA was encapsulated in large, unilamellar phospholipid vesicles (liposomes), and the encapsulated TMV RNA was shown to be infectious when incubated with tobacco protoplasts under appropriate conditions. Maximal virus production in protoplasts was observed after their incubation with TMV RNA entrapped in phosphatidylserine/cholesterol liposomes. Infection was dependen...
متن کاملProduction of secretory cutinase by recombinant Saccharomyces cerevisiae protoplasts
BACKGROUND During heterologous protein production using recombinant microbes, the protein tends to accumulate in the cell and may not be secreted. Here, we studied the production of secretory cutinase (heterologous protein) by recombinant Saccharomyces cerevisiae protoplasts. FINDINGS Recombinant S. cerevisiae cells (i.e., cells into which the cutinase gene was transferred) secreted trace amo...
متن کاملLocalization of acid phosphatase in protoplasts from Saccharomyces cerevisiae.
The localization of acid phosphatase (EC 3.1.3.2) in secreting protoplasts prepared from Saccharomyces cerevisiae is reported for the first time. Using a Gomori technique we were able to show acid phosphatase at those organelles in the protoplasts which are generally involved in the processes of biosynthesis and secretion of glycoproteins in eukaryotic cells.
متن کاملTransfer of Liposome-Sequestering Plasmid DNA into Daucus carota Protoplasts.
Reverse-phase evaporation lipid vesicles (REV) liposomes, consisting of phosphatidyl choline and stearylamine in 1:3 molar ratio, encapsulated approximately 30% of exogenously supplied recombinant DNA vector, pBR322. The DNA sequestered in REV liposomes was highly tolerant to DNase.A two-step procedure was developed, which involves encapsulation of DNA with liposomes using one-tenth phosphate-b...
