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.
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 .
In humans, the tyrosine aminotransferase protein is encoded by the TAT gene. [7] A deficiency of the enzyme in humans can result in what is known as type II tyrosinemia, wherein there is an abundance of tyrosine as a result of tyrosine failing to undergo an aminotransferase reaction to form 4-hydroxyphenylpyruvate. [8]
Tyrosine phosphorylation activity also increases or decreases in conjunction with changes in cell composition and growth regulation. In this way, a certain transformation exhibited by cells is dependent on a role that tyrosine kinase demonstrates. [5] Protein tyrosine kinases, have a major role in the activation of lymphocytes. In addition ...
l-DOPA is produced from the amino acid l-tyrosine by the enzyme tyrosine hydroxylase. l-DOPA can act as an l-tyrosine mimetic and be incorporated into proteins by mammalian cells in place of l-tyrosine, generating protease-resistant and aggregate-prone proteins in vitro and may contribute to neurotoxicity with chronic l-DOPA administration. [10]
Tyrosin-protein kinase Lck (or lymphocyte-specific protein tyrosine kinase) is a 56 kDa protein that is found inside lymphocytes and encoded in the human by the LCK gene. [5] The Lck is a member of Src kinase family (SFK) and is important for the activation of T-cell receptor (TCR) signaling in both naive T cells and effector T cells. The role ...
