The tyrosinase (Tyr) gene encodes the enzyme tyrosinase that catalyses the conversion of L-tyrosine into DOPA (3,4-dihydroxyphenylalanine)-quinone.The albino mutation abrogates functional activity ...

Cleome arabica, locally known as “Mnitna,” was also able to block tyrosinase activity but not as effectively as H. articulatum.

At the core of the mechanism is the activity of the enzyme tyrosinase. ... Tyrosinase initiates the melanin synthesis process. "We previously did not fully understand the role played by this enzyme.

Tyrosinase versus Catechol Oxidase: One Asparagine Makes the Difference. Angewandte Chemie International Edition , 2016; 55 (8): 2884 DOI: 10.1002/anie.201508534 Cite This Page : ...

"Our goal was to understand how cyclo(L-Pro-L-Tyr) disrupts tyrosinase activity," explained Dr. Furuyama. "In melanin biosynthesis, tyrosinase initially converts L-tyrosine (L-Tyr) to ...

Mushroom tyrosinase with L-tyrosine as substrate was used to evaluate anti-tyrosinase activity, elastase from porcine pancreas Type IV E0258 with N-Succinyl-Ala-Ala-Ala-p-nitroanilide (SANA) as ...
