Regulation and consequence of serine catabolism in Streptococcus pyogenes.

abstract：:Respiratory nitrate reductase purified from the cell membrane of Escherichia coli is composed of three subunits, alpha, beta, and gamma, which are encoded, respectively, by the narG, narH, and narI genes of the narGHJI operon.

abstract：:cat-86 is a promoter-deficient plasmid gene that encodes chloramphenicol acetyltransferase (CAT). Insertion of a promoter at a site 144 base pairs 5' to the cat-86 coding sequence activates transcription of the gene and allows cat-86 to specify chloramphenicol-inducible CAT activity in Bacillus subtilis. Induction of ...
