The degenerate electron exchange (DEE) reaction involving radical cations (RCs) of n-nonane, n-dodecane, and n-hexadecane in n-hexane solution was studied over the temperature range 253-313 K using the method of time-resolved magnetic field effect in recombination fluorescence of spin-correlated
Genes encoding cytochromes P450 of the CYP52 family in the n-alkane-assimilating yeast Yarrowia lipolytica have been cloned and analyzed. Degenerate PCR primers which were designed for the conserved amino acid sequences of cytochromes P450ALK of Candida species were used for amplification and
Perfluoroisobutylene a is pulmonotoxic chemical generated during pyrolysis of perfluoro-nalkanes (polytetrafluoroethylene). The mechanisms of acute pulmonary toxicity induced by perfluoroisobutylene have not been studied yet. The analysis of tissues of brown frogs showed that the products of
The generation of retention index (RI) libraries is an expensive and time-consuming effort. Procedures for the transfer of RI properties between chromatography variants are, therefore, highly relevant for a shared use. The precision of RI determination and accuracy of RI transfer between 8 method
We report the results from Mayer-sampling Monte Carlo calculations of the virial coefficients of the united-atom TraPPE-UA model of normal alkanes. For alkane chain lengths from n=2 to 20 (where n is the number of carbon atoms), results are given for the virial coefficients B(2), B(3), and B(4);
The sulfate-reducing strain AK-01 activates alkanes via addition of the subterminal carbon to the double bond of fumarate. This reaction is similar to the action of the glycyl radical enzyme benzylsuccinate synthase (Bss). It was hypothesized that strain AK-01 possesses a similar enzyme. Degenerate
We have developed highly degenerate oligonucleotides for polymerase chain reaction (PCR) amplification of genes related to the Pseudomonas oleovorans GPo1 and Acinetobacter sp. ADP1 alkane hydroxylases, based on a number of highly conserved sequence motifs. In all Gram-negative and in two out of
Many bacteria have been reported as degraders of long-chain (LC) n-alkanes, but the mechanism is poorly understood. Flavin-binding monooxygenase (AlmA) was recently found to be involved in LC-alkane degradation in bacteria of the Acinetobacter and Alcanivorax genera. However, the diversity of this
