Tyrosinase is a highly conserved protein in animals and apparently arose already in bacteria. The tyrosinase related protein (Tyrp1) and dopachrome tautomerase (Dtc), which encode for protein implicated in melanin synthesis which are the common regulatory elements of exon/intron structure.

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.
Several skin whitening agents, including tyrosinase inhibitors, have been found to cause an increase in the expression of tyrosinase, which by itself would increase melanin synthesis. [ 43 ] Microphthalmia-associated transcription factor (MITF) is the master transcription factor that controls the expression of TYR, TRP1, and TRP2, MART1 ...
The enzyme tyrosine phenol-lyase (EC 4.1.99.2) catalyzes the chemical reaction. L-tyrosine + H 2 O phenol + pyruvate + NH 3. This enzyme belongs to the family of lyases, specifically in the "catch-all" class of carbon-carbon lyases.
Tyrosinase is an enzyme needed in melanin synthesis in the melanin producing cell of the skin, the melanocyte. By reducing the activity of tyrosinase, β-arbutin reduces the synthesis of melanin, leading to a lighter skin tone and the diminished appearance of hyperpigmentation. It is not as potent an inhibitor of tyrosinase as α-arbutin. [6]
Cartoon representation of the molecular structure of protein domain: p56 lck tyrosine kinase. Tyrosine phosphorylation is the addition of a phosphate (PO 4 3−) group to the amino acid tyrosine on a protein.
A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to the tyrosine residues of specific proteins inside a cell. It functions as an "on" or "off" switch in many cellular functions.
