Chemotaxis to Hydrocarbons, carbon and energy for many bacterial species, have been shown to be chemoattractants for specific organisms. While much is known about catabolic pathways for the degradation of hydrocarbons and related compounds, less is known about the molecular basis for chemotactic responses to these volatile an

, Isomerase of Unsaturated Fatty Acids: An Immediate Bacterial Adaptive Mechanism to Cope with Emermpounds is the isomerization of .- to .-unsaturated membrane fatty acids. The degree of isomerization obviously depends on the toxicity and the concentration of membrane-affecting agents. Synthesis of .fatty acids comes about by direct isomerization of the respective .-configuration of the double bo

DNA Methylation in Prokaryotes: Regulation and Function,eukaryotes, the most important methylation in bacteria takes place on adenines (in position N6). The enzymes responsible for DNA methylation are often associated with restriction enzymes acting as a defense mechanism against foreign DNA (Restriction-Modification or R-M system). Other methyltransfera

Extrusion Pumps for Hydrocarbons: An Efficient Evolutionary Strategy to Confer Resistance to Hydrocof three components. Two components are transmembrane proteins located in the inner and outer membrane whereas the third one spans the periplasm connecting the other two subunits. The large part of information available on RND pumps is related to their capacity to extrude antibiotics. Structural dat

Genetics of Sensing, Accessing, and Exploiting Hydrocarbons,cules. In order to achieve this, bacteria have developed specific sensor proteins and adaptive mechanisms. In the presence of hydrocarbons, the bacterial adaptive response is modulated at the transcriptional and post-transcriptional levels by one- and two-component regulatory systems, global regulat

Hydrophobic Modifications of Biomolecules: An Introduction,y coding elements of their sequences. Some of the bases in the DNA and RNA and the majority of the amino acids in the protein can incorporate new functional groups through a covalent addition. By means of these modifications, the genetically encoded functions of active proteins or the expression pat

Kinetics and Physiology at Vanishingly Small Substrate Concentrations, along with other classes of organics. Concentrations are small, in the μg L. range and generally below detection. The organisms are sometimes mischaracterized as high-affinity organisms due to small Michaelis constants, and measured affinities for these and other substrates of oligobacteria are muc
