Genetics of methyl-accepting chemotaxis proteins in Escherichia coli: organization of the tar region.

abstract：:A method has been developed for studying the specific activity of the pool of S-adenosylmethionine in yeast. The pool reaches half-maximal specific activity within 30 s after the addition of [methyl-3H]methionine. After addition of an excess of nonradioactive methionine, the specific activity of S-adenosylmethionine i...
