Pyruvate decarboxylase activity is regulated by the Ser/Thr protein phosphatase Sit4p in the yeast Saccharomyces cerevisiae.
FEMS Yeast Res. 13(6) , 518-28, (2013) Deletion of SIT4 phosphatase decreased the pyruvate decarboxylase activity, which is essential for directing the glucose flux to ethanol production. Concomitantly, a reduction in the fermentative capacity was observed. As pyruvate decarboxylase expression was... |

Computational, structural, and kinetic evidence that Vibrio vulnificus FrsA is not a cofactor-independent pyruvate decarboxylase.
Biochemistry 52(11) , 1842-4, (2013) The fermentation-respiration switch (FrsA) protein in Vibrio vulnificus was recently reported to catalyze the cofactor-independent decarboxylation of pyruvate. We now report quantum mechanical/molecular mechenical calculations that examine the energetics of C... |

Genetic engineering to enhance the Ehrlich pathway and alter carbon flux for increased isobutanol production from glucose by Saccharomyces cerevisiae.
J. Biotechnol. 159(1-2) , 32-7, (2012) The production of higher alcohols by engineered bacteria has received significant attention. The budding yeast, Saccharomyces cerevisiae, has considerable potential as a producer of higher alcohols because of its capacity to naturally fabricate fusel alcohols... |

Substrate specificity of thiamine pyrophosphate-dependent 2-oxo-acid decarboxylases in Saccharomyces cerevisiae.
Appl. Environ. Microbiol. 78(21) , 7538-48, (2012) Fusel alcohols are precursors and contributors to flavor and aroma compounds in fermented beverages, and some are under investigation as biofuels. The decarboxylation of 2-oxo acids is a key step in the Ehrlich pathway for fusel alcohol production. In Sacchar... |

Chlamydomonas reinhardtii chloroplasts contain a homodimeric pyruvate:ferredoxin oxidoreductase that functions with FDX1.
Plant Physiol. 161(1) , 57-71, (2013) Eukaryotic algae have long been known to live in anoxic environments, but interest in their anaerobic energy metabolism has only recently gained momentum, largely due to their utility in biofuel production. Chlamydomonas reinhardtii figures remarkably in this... |

Catalytically active filaments - pyruvate decarboxylase from Neurospora crassa. pH-controlled oligomer structure and catalytic function.
FEBS J. 279(2) , 275-84, (2012) Pyruvate decarboxylase is a key enzyme in organisms whose energy metabolism is based on alcoholic fermentation. The enzyme catalyses the nonoxidative decarboxylation of 2-oxo acids in the presence of the cofactors thiamine diphosphate and magnesium ions. Pyru... |

The high fermentative metabolism of Kluyveromyces marxianus UFV-3 relies on the increased expression of key lactose metabolic enzymes.
Antonie van Leeuwenhoek 101(3) , 541-50, (2012) The aim of this work was to obtain insights about the factors that determine the lactose fermentative metabolism of Kluyveromyces marxianus UFV-3. K. marxianus UFV-3 and Kluyveromyces lactis JA6 were cultured in a minimal medium containing different lactose c... |

Fed-batch system for cultivating genetically engineered yeast that produces lactic acid via the fermentative promoter.
J. Biosci. Bioeng. 115(2) , 193-5, (2013) A simple fed-batch system for cultivating genetically engineered yeast generating lactate under the regulation of the PDC1 promoter was established. Traditional strategies that avoid occurrence of Crabtree effect, such as respiratory quotient (RQ) control or ... |

Physiological tests for yeast brewery cells immobilized on modified chamotte carrier.
Antonie van Leeuwenhoek 104(5) , 703-14, (2013) In this study yeast cell physiological activity was assessed on the basis of the in situ activity of two important enzymes, succinate dehydrogenase and pyruvate decarboxylase. FUN1 dye bioconversion and cellular ATP content were also taken as important indica... |

Role of antioxidant and anaerobic metabolism enzymes in providing tolerance to maize (Zea mays L.) seedlings against waterlogging.
Indian J. Biochem. Biophys. 48(5) , 346-52, (2011) The present investigation was undertaken to identify the possible mode of mechanism that could provide tolerance to maize (Zea mays L.) seedlings under waterlogging. Using cup method, a number of maize genotypes were screened on the basis of survival of the s... |
