Hi,

Are Catechol Oxidase, Polyphenol Oxidase and Tyrosinase the same enzyme?

Many thanks

Cis or trans? That's what matters.

Complete and the full length cDNA sequence of poly phenol oxidase, cDNA from grape Vitis vinifera L., cv Grenache, was found to encode a translated protein of amino acids with an expected molecular weight of ca.kDa and a predicted pI of 6.83. The translated amino acid sequence was 99%, identical to that of a white grape berry PPO (1)(5 out of 607 amino acid potential sequence differences. The protein was purified from Grenache grape berries by using traditional methods, and it was crystallized with ammonium acetate by the hanging-drop vapor diffusion method.
History will be kind to me, for I intend to write it.

What's the difference between L-amino acid oxidase and D-amino acid oxidase?
