The two-component flavoenzyme styrene monooxygenase (SMO) is an efficient alternative to several chemical epoxidation catalysts on a preparative scale. A first homology model of the catalytic domain (StyA) of SMO was constructed (Protein Data Bank ID 2HD8) based on the structure of para-hydroxybenzoate hydroxylase. The StyA protein structure was optimized by restrained molecular dynamics to rep...
The anaerobic biodegradation of m-cresol was observed in anoxic aquifer slurries kept under both sulfate-reducing and nitrate-reducing but not methanogenic conditions. More than 85% of the parent substrate (300 microM) was consumed in less than 6 days in slurries kept under the former two conditions. No appreciable loss of the compound from the corresponding autoclaved controls was measurable. ...
p-Hydroxybenzoate hydroxylase (EC 1.14.13.2) from Pseudomonas desmolytica is known to form a stable complex with its substrate. Investigations were made on properties of the complex by spectrophotometric measurements and photooxidation. The addition ofp-hydroxybenzoate or benzoate to the oxidized (with respect to bound FAD) enzyme solution caused changes in absorption, fluorescence, and CD spec...
IS1071 is a class II transposable element carrying a tnpA gene related to the transposase genes of the Tn3 family. Copies of IS1071 that are conserved with more than 99% nucleotide sequence identity have been found as direct repeats flanking a remarkable variety of catabolic gene sequences worldwide. The sequences of chlorobenzoate catabolic transposons found on pBRC60 (Tn5271) in Niagara Falls...
we give the concept of ‘braiding’ for 2-groupoids, and we show that this structure is equivalent tobraided regular, crossed modules.
S1. Comment: Tyramine Ferulates in Tobacco Lignins Tobacco lignins were found to have a substantial component derived from tyramine ferulate. The levels of this component appeared elevated in certain CCRand CAD-deficient transgenics (Ralph et al., 1998). Although we were careful to note that tyramine ferulate is a wellknown wound-response product in tobacco, we remained convinced by the correla...
