This invention provides a method for producing proteins into which non-natural amino acids have been incorporated at desired positions involving the use of either prokaryote-derived or eukaryote-type aaRS* and prokaryotic cells or eukaryote-type as host cells, the method comprising steps of: (a) introducing genes encoding prokaryote-derived aminoacyl tRNA synthetase mutants having enhanced specificity to non-natural amino acids similar to given natural amino acids (compared with specificity to the natural amino acids) and tRNA genes for non-natural amino acids capable of binding to the non-natural amino acids in the presence of the prokaryote-derived aminoacyl tRNA synthetase mutants into prokaryotic cells that express genes encoding eukaryote-type aminoacyl tRNA synthetase having specificity to the given natural amino acids and tRNA genes capable of binding to the natural amino acids in the presence of eukaryote-type aminoacyl tRNA synthetase; and (b) knocking out genes encoding aminoacyl tRNA synthetase having specificity to the natural amino acids, which are inherent in the prokaryotic cells, and inherent tRNA genes capable of binding to the natural amino acids in the presence of the inherent aminoacyl tRNA synthetase.
The invention provides compositions and methods of identifying, modifying and producing modified target molecules, including therapeutic molecules by modification with non-natural amino acids. Certain aspects of the invention include methods of adding a chemical moiety to a target molecule, and the compositions resulting therefrom. Certain aspects of the invention also relate to kits for identifying, modifying and producing modified target molecules described herein.
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.
描述了一种测量蛋白质特性的仪器,该仪器包括一个 X 射线荧光 (XRF) 光谱仪,其中包括一个多色 X 射线源、一个 X 射线探测器、一个蛋白质、一个已暴露于该蛋白质并至少与该蛋白质弱结合的分子、通过用多色 X 射线照射蛋白质和分子中的化学元素而获得的多个 X 射线荧光信号数据,以及一个用于维护多个 X 射线荧光信号测量数据记录的安全系统。此外,还介绍了一种用于测量样品的 X 射线显微镜。
