  2. Tyrosine - Wikipedia

    en.wikipedia.org/wiki/Tyrosine

    Tyrosine ball and stick model spinning. L-Tyrosine or tyrosine (symbol Tyr or Y) [2] or 4-hydroxyphenylalanine is one of the 20 standard amino acids that are used by cells to synthesize proteins. It is a conditionally essential amino acid with a polar side group.

  3. Tyrosine kinase - Wikipedia

    en.wikipedia.org/wiki/Tyrosine_kinase

    Tyrosine kinase activity in the nucleus involves cell-cycle control and properties of transcription factors. [3] In this way, in fact, tyrosine kinase activity is involved in mitogenesis, or the induction of mitosis in a cell; proteins in the cytosol and proteins in the nucleus are phosphorylated at tyrosine residues during this process. [3]

  5. Tyrosine hydroxylase - Wikipedia

    en.wikipedia.org/wiki/Tyrosine_hydroxylase

    Tyrosine hydroxylase or tyrosine 3-monooxygenase is the enzyme responsible for catalyzing the conversion of the amino acid L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA). [ 5 ] [ 6 ] It does so using molecular oxygen (O 2 ), as well as iron (Fe 2+ ) and tetrahydrobiopterin as cofactors .

  6. Receptor tyrosine kinase - Wikipedia

    en.wikipedia.org/wiki/Receptor_tyrosine_kinase

    Receptor tyrosine kinases (RTKs) are the high-affinity cell surface receptors for many polypeptide growth factors, cytokines, and hormones. Of the 90 unique tyrosine kinase genes identified in the human genome , 58 encode receptor tyrosine kinase proteins. [ 1 ]

  7. Tyrosine phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Tyrosine_phosphorylation

    Tyrosine phosphorylation is the addition of a phosphate (PO 4 3−) group to the amino acid tyrosine on a protein. It is one of the main types of protein phosphorylation. This transfer is made possible through enzymes called tyrosine kinases. Tyrosine phosphorylation is a key step in signal transduction and the regulation of enzymatic activity.

  8. Tyrosinemia - Wikipedia

    en.wikipedia.org/wiki/Tyrosinemia

    It is a 4-hydroxyphenylpyruvate dioxygenase inhibitor indicated for the treatment of hereditary tyrosinemia type 1 (HT-1) in combination with dietary restriction of tyrosine and phenylalanine. [7] Liver transplant is indicated for patients with tyrosinemia type I who do not respond to nitisinone, as well as those with acute liver failure and ...
