TL;DR: Direct evidence was obtained for 3'-to-5' directionality in the decay of the long-lived mRNA encoded by the ompA gene, and no preferential stability was observed for translated versus untranslated mRNA segments.

TL;DR: Two separate enzymes, which determine resistance to inorganic mercury and organomercurials, have been purified from the plasmid-bearing Escherichia coli strain J53-1(R831), suggesting that the native enzyme is composed of three identical subunits.

TL;DR: THE AUTHORS have screened a large number of R plasmid-bearing Escherichia coli and obtained a few that confer resistance to the organomercurials phenylmercuric acetate (PMA) and methylmerCuric chloride (MMA), which are of interest to see if the mercury(ial) resistance of the bacteria in the alimentary canal influences the fate of ingested mercury(ials).

TL;DR: Selectable plasmid vectors that contain a gene encoding resistance to the antibiotic methylenomycin A and that are suitable for the cloning of endonuclease-generated DNA fragments in Streptomyces species have been constructed and characterised.

TL;DR: The crystal structure of a novel esterase from Streptomyces scabies, a causal agent of the potato scab disease, was solved at 2.1 Å resolution and constitutes the first known natural variation of the chymotrypsin-like triad in which a carboxylic acid is replaced by a neutral hydrogen-bond acceptor.
