Analogue EHW Chip for Intermediate Frequency Filters
This paper describes an analogue EHW (Evolvable Hardware) chip for Intermediate Frequency (IF) lters, which are widely used in cellular phones. When analogue Integrated Circuits (ICs) and LargeScale Integrated Circuits (LSIs) are manufactured, the values of the analogue circuit components, such as resistors or capacitors, often vary from the precise design speci cations. Analogue LSIs with such...
متن کاملEfficiently Activated Serine Analogue is Not Transferred to Yeast tRNA
Covalent attachment of cognate amino acid to the cognate tRNA is a prerequisite for the faithful synthesis of proteins in the cell. Aminoacylation of tRNA, catalyzed by aminoacyl-tRNA synthetases (aaRSs), proceeds by a two-step reaction whereby amino acid is first activated and then transferred to the 3'-ribose of tRNA. Serine hydroxamate (SerHX) is an interesting analogue of serine as it exhib...
متن کاملGlutamyl Phosphate Is an Activated Intermediate in Actin Crosslinking by Actin Crosslinking Domain (ACD) Toxin
Actin Crosslinking Domain (ACD) is produced by several life-threatening Gram-negative pathogenic bacteria as part of larger toxins and delivered into the cytoplasm of eukaryotic host cells via Type I or Type VI secretion systems. Upon delivery, ACD disrupts the actin cytoskeleton by catalyzing intermolecular amide bond formation between E270 and K50 residues of actin, leading to the formation o...
متن کاملAn Optical Analogue Fourier Transformer
The design and construction of a simple optical analogue Fourier transform computer is described. The instrument which uses MoirB fringes to form a variable spatial frequency filter is intended to produce approximate spectra from interferograms in about five minutes. Results obtained with the instrument are shown. ime to time a number of analogue Fourier transform computers have been described,...
متن کاملIntermediate Tyrosyl Radical and Amyloid Structure in Peroxide-Activated Cytoglobin
We characterized the peroxidase mechanism of recombinant rat brain cytoglobin (Cygb) challenged by hydrogen peroxide, tert-butylhydroperoxide and by cumene hydroperoxide. The peroxidase mechanism of Cygb is similar to that of myoglobin. Cygb challenged by hydrogen peroxide is converted to a Fe4+ oxoferryl π cation, which is converted to Fe4+ oxoferryl and tyrosyl radical detected by direct cont...
