Bacterium coli, inoculated in broth, metabolizes the culture medium producing alkalinization, bringing the pH to 8.5 and more. These are the standard conditions we used to obtain penicillinase1.

Introduction of str A mutations frequently make "male" strains of Escherichia coli permissive to bacteriophage T7; certain rif mutations reverse the permissive effect of strA mutation. Permissiveness of the strA mutation is accompanied by enhanced tr

The regulation profiles of OTCase (argF, argI) synthesis in vitro were investigated by using the in vitro system described in the accompanying paper. Addition of 2.6 mM arginine, crude repressor and partially purified repressor to the in vitro system

Two genes for ornithinetranscarbamylase exist in strain Escherichia coli K-12, argI, at 85 min, and argF, at 7 min. In an attempt to compare the deoxyribonucleic acid material of these two genes, the lambda transducing phages carrying a portion of th

Evidence is presented suggesting that streptomycin binds to 16S RNA or to 30S ribosomal subunits at the same topographical site located on the RNA chain. The equally bactericidal dihydrostreptomycin binds to the same site as streptomycin but with low

An in vitro system for the synthesis of ornithine transcarbamylase (OTCase) was established using iS-30 extract from E. coli MDS6-2(lambda) and DNA of a lambda transducing phage carrying argI and argF genes. This in vitro synthesis was completely dep

A temperature-sensitive lethal mutant of Escherichia coli has been constructed by combining two temperature-insensitive mutations: a rif180 mutation that modifies RNA polymerase (RNA nucleotidyltransferase; nucleosidetriphosphate:RNA nucleotidyltrans

Resume L'etude de l'influence du calcium sur la denaturation de la trypsine a p h 7.9 par la chaleur, montre que le calcium ralentit considerablement la denaturation de l'enzyme et que tout substance, comme la Complexone II, capable de donner avec le

16 lac frameshift mutants induced by an acridine derivative, ICR-191D, in E. coli are leaky for β-galactosidase activity. Activities of all mutants differ from each other and from the wild type in their stability to thermal denaturation. The leakine

Lysis of the cells of M. lysodeikticus by lysozyme is only accompanied by proteolysis if a certain amount of calcium is added to the medium. This fact shows that, at the moment of lysis of the cells, they contain potentially the proteinases necessary
