Tyrosine
Tyrosine (Tyr, Y, 4-hydroxyphenylalanine, C9H11NO3) is a nonessential aromatic amino acid made from phenylalanine; discovered in casein by Liebig in 1846, it is the precursor of catecholamines, thyroid hormones, and melanin.
Tyrosine 3-monooxygenase-like, ACT domain
Tyrosine 3-monooxygenase-like, ACT domain (IPR049321): the ACT-domain fold in the N-terminal regulatory domain of tyrosine hydroxylase; a ferredoxin-like βαββαβ dimerizing regulatory module, allosteric in most homologs but non-allosteric in tyrosine hydroxylase.
Tyrosine aminotransferase
Tyrosine aminotransferase (TAT, EC 2.6.1.5, tyrosine transaminase) is a PLP-dependent liver cytosolic enzyme converting L-tyrosine plus 2-oxoglutarate to 4-hydroxyphenylpyruvate and glutamate; deficiency causes tyrosinemia type II.
Tyrosine catabolism
Tyrosine catabolism: the five-step degradation of tyrosine via 4-hydroxyphenylpyruvate, homogentisate, and fumarylacetoacetate to fumarate and acetoacetate; enzyme defects cause tyrosinemia and alkaptonuria.
Tyrosine hydroxylase
Tyrosine hydroxylase (TH, EC 1.14.16.2), a non-heme iron, BH4-dependent homotetrameric enzyme, catalyzes the rate-limiting conversion of L-tyrosine to L-DOPA in catecholamine biosynthesis; regulated by catecholamine feedback inhibition and Ser40 phosphorylation; its deficiency causes dopa-responsive dystonia and infantile parkinsonism.
Tyrosine kinase
Tyrosine kinase (protein-tyrosine kinase): enzyme transferring ATP gamma phosphate to protein tyrosine residues. 90 human genes (58 receptor, 32 non-receptor); SH2/PTB-docked signaling; imatinib-paradigm drug targets.
Tyrosine kinase inhibitor therapy
Tyrosine kinase inhibitor (TKI) therapy is targeted drug treatment with small molecules that block the ATP-binding site of tyrosine kinases, stopping the signaling cancer cells use to grow and survive.
Tyrosine kinase oncogenes and fusion proteins
Tyrosine kinase oncogenes and fusion proteins are growth-signaling kinase genes locked on by retroviral capture or chromosomal fusion, driving cancers such as BCR-ABL-positive chronic myeloid leukemia, treatable with imatinib.
Tyrosine phenol-lyase
Tyrosine phenol-lyase (TPL, EC 4.1.99.2, beta-tyrosinase) is a PLP-dependent bacterial tetrameric lyase cleaving L-tyrosine to phenol, pyruvate, and ammonia, and catalyzing the industrial one-step biosynthesis of L-DOPA from pyrocatechol, pyruvate, and ammonia.
Tyrosine recombinase XerD-like
Tyrosine recombinase XerD-like proteins are the XerD branch of tyrosine site-specific recombinases, including XerD itself, XerH, XerS, and archaeal XerA, which resolve circular chromosome dimers at dif sites and are hijacked by mobile elements such as CTXφ.
Tyrosine-protein kinase SYK
Tyrosine-protein kinase SYK (spleen tyrosine kinase), a nonreceptor tyrosine kinase with tandem SH2 domains, initiates B cell receptor signaling; autoinhibited until ITAM binding and phosphorylation, distinct from ZAP70, targeted by inhibitors.

Tyrosine—tRNA ligase
Tyrosine—tRNA ligase (tyrosyl-tRNA synthetase, TyrRS, YARS1) is the class I aminoacyl-tRNA synthetase that charges tRNA-Tyr with tyrosine; a functional dimer with class II-like tRNA binding, linked to dominant peripheral neuropathy.
