Examples

  • By re-programming the code of a DNA molecule, e.g. changing the word CAC to GAC, it would be possible to obtain a protein in which the amino acid histidine is replaced by the amino acid aspartic acid.

    Press Release: The 1993 Nobel Prize in Chemistry

  • The gene containing the bacteria's LOV domain also codes for a signaling protein called a histidine kinase.

    News from The Scientist

  • The gene containing the bacteria's LOV domain also codes for a signaling protein called a histidine kinase.

    News from The Scientist

  • Amino acids, such as histidine, produced by pathways related to nucleotide metabolism, but not found in spark-tube experiments, are in fact excellent candidates for inclusion because they interact well with the RNA that must be present.

    An Interesting Pattern

  • P. falciparum cultures should be evaluated, and the putative implication of particular ROS determined using reversible inhibitors such as histidine, tryptophan, superoxide dismutase and/or catalase, to indicate which oxygen radicals, if any, are involved

    PLoS ONE Alerts: New Articles

  • The amino acids are arginine, histidine, isoleucine, lysine and methionine.

    The Burning Wire

  • The amino acids are arginine, histidine, isoleucine, lysine and methionine.

    The Burning Wire

  • A2 cows produce this protein with a proline at number 67, whereas A1 cows have a mutated proline amino acid, which converts it to histidine.

    Dr. Joseph Mercola: Why You Shouldn't Drink Pasteurized Milk

  • This idea is reemphasized here in the finding that amino acids with complex biosyntheses, like tryptophan, histidine, and arginine, were included in the presumably primordial stereochemical core of the genetic code.

    An Interesting Pattern

  • The main sources of histidine are all root and green leafy vegetables.
