Efficient Gene Transfer in Bacterial Cell Chains

Horizontal gene transfer contributes to evolution and the acquisition of new traits. In bacteria, horizontal gene transfer is often mediated by conjugative genetic elements that transfer directly from cell to cell. Integrative and conjugative elements (ICEs; also known as conjugative transposons) are mobile genetic elements that reside within a host genome but can excise to form a circle and tr...

Cyanide-sensitive Bacterial Respiratory Systems

In previous communications (Sevag and Shelburne, 1942) it was shown that sulfonamide drugs inhibited the aerobic respiration and anaerobic glycolysis of Streptococcus pyogenes and the respiration of pneumococcus Type 1. The inhibition of respiration could take place in the absence of growth. In the presence of growth the inhibition of respiration and of growth occurred to the same relative exte...

Oxidative Phosphorylation in Fractionated Bacterial Systems XVIII. PHOSPHORYLATION COUPLED TO DIFFERENT SEGMENTS OF THE RESPIRATORY CHAINS OF MYCOBACTERIUM PHLEI*

A number of bacterial systems have been described which will carry out oxidative phosphorylat,ion (1-12). In general these systems differ from intact mammalian mitochondrial systems in that the bacterial systems have lower P:O ratios and fail to exhibit respiratory control. Loss of sites of phosphorylation (13, 14) and nonphosphorylative electron transport bypass reactions (13, 15-18) has been ...
