Rgg regulates growth phase-dependent expression of proteins associated with secondary metabolism and stress in Streptococcus pyogenes.

abstract：:The major cotransduction gap of the Escherichia coli chromosome extends from mini 31 to 34. We have inserted transposons through this gap which, by sequential transduction, link sbcA (min 29.8) with manA (min 35.7) and thus eliminate the gap. These results indicate that the length of DNA in the region, as measured by ...

abstract：:Although Salmonella typhimurium prefers neutral-pH environments, it can adapt to survive conditions of severe low-pH stress (pH 3.3). The process, termed the acid tolerance response (ATR), includes two distinct stages. The first stage, called pre-acid shock, is induced at pH 5.8 and involves the production of an induc...
