Application
L-Tyrosine was used in tyrosine hydroxylase (TH) enzyme activity assay.[1] It was also used as a substrate for tyrosinase enzyme in the growth media of Vibrio cholerae strains to stimulate melanin formation.[2] It may be used as a precursor in the synthesis of (-)-MY 336a. MY 336a, a β-adrenergic receptor antagonist, was initially isolated from the culture broth of Streptomyces gabonae KY2234 (ATCC 15282).[3] It may be used in the synthesis of 3-bromo-L-tyrosine and 3,5-dibromo-L-tyrosine.[4]

Vibrio cholerae synthesized the pigment melanin in response to specific physiological conditions that were stressful to the bacterium. Pigmentation was induced when V. cholerae was subjected to hyperosmotic stress in conjunction with elevated growth temperatures (above 30 degrees C). The

Tyrosine hydroxylase (TH) catalyzes the conversion of L-tyrosine to L-dihydroxyphenylalanine (L-DOPA), the rate-limiting step in the biosynthesis of dopamine. Recently, we described a point mutation in hTH (Q381K) in a family of two siblings suffering from progressive L-DOPA-responsive dystonia (DRD)

L-Tyrosine is converted to 3-bromo-L-tyrosine in good yield by reaction with 1.2 equiv. of DMSO in HBr/AcOH, while reaction with 2.2 equiv. of DMSO under comparable conditions results in formation of 3,5-dibromo-L-tyrosine in good yield. This is the simplest, safest
