The past ten years of developmental genetics have revealed that most of our genes are shared by other species throughout the animal kingdom. Consequently, animal diversity might largely rely on the differential use of the same components, either at the ind ...
Combinatorial mutagenesis was used to investigate the role of three key residues in cytochrome c peroxidase (CCP) from Saccharomyces cerevisiae, Arg48, Trp51, and Trp191, in control of the reactivity and selectivity of the heme-contg. enzyme. Libraries wer ...
The syntheses of azaMan-beta-(1-->6)-C-Glc (4), azaGlc-beta-(1-->6)-C-Glc (5), and azaGal-beta-(1-->6)-C-Glc (6) based upon double reductive amination of acetylenic carbohydrate-derived diketones is described. The required diketones are obtained by additio ...
Ab initio mol. dynamics (AIMD) and combined Hybrid/AIMD simulations appear as promising candidates for an in situ modeling of enzymic reactions. In order to probe the capabilities of these methods for the characterization of enzymic processes we have chose ...
The nucleotide sequence of a 6.5 kilobasepair chromosomal DNA fragment encoding the anaerobic dimethylsulphoxide (DMSO) reductase operon of Escherichia coli has been determined. The DMSO reductase structural operon was shown to consist of three open readin ...
The aim of the invention is to improve existing amperometric sensors used to measure the quantity of a component present in a solution. This aim is reached by using a sensor provided with a measuring electrode (20) having at least one current collector (37 ...
The influence of temp. on the catalytic activity and deactivation of sol. enzymes which are com. used in batch processes is discussed. Since high temp. not only accelerates the desired enzymic reaction but also the undesired deactivation of the enzyme, it ...
We have developed a simple and accurate isocratic HPLC method, without any prederivatisation, for the determination of glucose, lactate, glutamine, glutamate, pyrrolidone carboxylic acid and alanine in samples from mammalian cell cultures. The method has b ...
Vibrio and Aeromonas spp. secrete an unusual 35-kDa lipase that shares several properties with mammalian lecithin-cholesterol acyltransferase. The Aeromonas hydrophila lipase contains two cysteine residues that form an intramolecular disulfide bridge. Here ...
Enzymic hydrolyses of naturally occurring protein sources represent complex reactions at a molecular level because of the specificity pattern of proteases and the composition of the substrates involved. In addition, rather global criteria are in practical ...
