Biochemical and molecular characterization of Saccharomyces cerevisiae strains ...
Oliveira, Valdinéia Aparecida; Vicente, Maristela Araújo; Fietto, L. G.; Castro, I. M.; Coutrim, Maurício Xavier; Schuller, Dorit; Alves, HenriqueSaccharomyces cerevisiae strains from different regions of Minas Gerais, Brazil, were isolated and characterized aiming at the selection of starter yeasts to be used in the production of cachac¸a, the Brazilian sugar cane spirit. The methodology established took into account the screening for biochemical traits desirable in a yeast cachaça producer, such as no H2S production, high tolerance to ethanol and high ...
Deficiency of Pkc1 activity affects glycerol metabolism in Saccharomyces cerevi...
Gomes, K. N.; Freitas, S. M. A. C.; Pais, T. M.; Fietto, J. L. R.; Totola, A. H.; Arantes, R. M. E.; Martins, A.; Lucas, C.; Schuller, DoritIn press ; Protein kinase C is apparently involved in the control of many cellular systems: the cell wall integrity pathway, the synthesis of ribosomes, the appropriated reallocation of transcription factors under specific stress conditions and also the regulation of N-glycosylation activity. All these observations suggest the existence of additional targets not yet identified. In the context of the control of...
Relationship between Protein kinase C and derepression of different enzymes
Salgado, A. C. P.; Schuller, Dorit; Casal, Margarida; Leão, Cecília; Leiper, F. C.; Carling, D.; Fietto, L. G.; Tropia, M. J.; Castro, I. M.The PKC1 gene in the yeast Saccharomyces cerevisiae encodes for protein kinase C which is known to control a MAP kinase cascade consisting of different kinases: Bck1, Mkk1 and Mkk2, and Mpk1. This cascade affects the cell wall integrity but the phenotype of pkc1∆ mutants suggests additional targets that have not yet been identified [1]. The pkc1∆ mutant, as opposed to other mutants in the MAP kinase cascade, di...
