Function of S-adenosylmethionine in germinating yeast ascospores.

abstract：:In the photosynthetic bacterium Rhodobacter capsulatus, the enzyme DNA gyrase has been implicated in the expression of genes for anaerobic metabolic processes such as nitrogen fixation and photosynthesis. To assess the involvement of supercoiling in anaerobic gene expression, we have developed an assay to detect in vi...
