In the last few years, the emergence of complete genome sequences has had profound effects on all fields of biology. While the existence of these genome sequences has served to facilitate experimental work, it has also highlighted the gaps in our knowledge of bacterial metabolism. Our current knowledge of metabolism is primarily the result of data accumulated from decades of study by biochemists and...
Expression of the cobalamin biosynthetic (cob) and 1,2-propanediol utilization (cob/pdu) regulon of Salmonella typhimurium LT2 is controlled at the transcriptional level by global and specific regulatory proteins. In this paper we show that mutations in the mviA gene negatively affect cob/pdu transcription in response to 1,2-propanediol in the environment. The effects of mviA mutations were consistent...
