Tungsten and molybdenum regulation of formate dehydrogenase expression in Desulfovibrio vulgaris Hildenborough.

abstract：:The Gram-positive bacterium Streptococcus pyogenes (also called group A Streptococcus [GAS]), is found strictly in humans and is capable of causing a wide variety of infections. Here we demonstrate that serine catabolism in GAS is controlled by the transcriptional regulator Spy49_0126c. We have designated this regulat...
