Pathway in a particle: A five‐enzyme biosynthetic pathway was self‐immobilized to form a single biocatalyst for generation of purine nucleotideanalogues from D‐ribose. This method provides an alternative to engineering biosynthetic pathways in whole cells that obviates problems associated with toxicity, transport and genetic regulation.
There is described an apparatus for measuring protein characteristics comprising an X-ray fluorescence (XRF) spectrometer comprising a source of polychromatic X-rays, an X-ray detector, a protein, a molecule that has been exposed to and at least weakly binds to the protein, a plurality of X-ray fluorescence signal data obtained by irradiating chemical elements in the protein and molecule with the polychromatic X-rays and a security system for maintaining records for the data from the plurality of X-ray fluorescence signal measurements. There is also described an x-ray microscope for measuring a sample.

Amino acids present in domains of an umami taste receptor are described herein, wherein the amino acids interact with at least one nucleotide derivative and/or at least one transmembrane compound that potentiates, modulates, increases, and/or enhances the activity of the umami receptor. Such compounds can be used in flavor compositions to enhance the umami taste and/or palatability of food products.
