Yeast PHO Genes: An Excellent Model for Elucidation of Chromatin-Remodelling Mechanisms
transcriptional regulation chromatin remodelling yeast PHO genes
2010/12/21
Nucleosomes, the basic units of chromatin structure, repress transcription by restricting
access of transcription factors to promoter cis-regulatory elements. It has recently become
clearly evident ...

The Effect of ATP Sulphurylase on the Prooxidant Properties of Selenate in Yeast Schizosaccharomyces pombe
ATP sulphurylase Schizosaccharomyces pombe selenate
2009/8/10
Selenium is an essential microelement in human and animal nutrition, whose intake can be in inorganic (e.g. selenite, selenate) or organic form (e.g. selenomethionine). The prooxidant effect of inorga...
Pyruvate Decarboxylase Activity Assay in situ of Different Industrial Yeast Strains
enzymatic activity in situ pyruvate decarboxylase yeasts
2009/6/24
Cytoplasmic pyruvate decarboxylase (PDC, EC 4.1.1.1) is one of the key enzymes of yeast fermentative metabolism. PDC is the first enzyme which, under anaerobic conditions, leads to decarboxylation of ...
