Activity of mushroom tyrosinase on catechol and on a catechol estrogen in an organic solvent

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1993
A suspension of tyrosinase-coated glass beads in butanol effectively oxidizes catechol substrate. The enzyme is not soluble in the organic solvent and activity can be stopped by removal of the solid state enzyme after low-speed centrifugation or decantation.

Interactions Between Estrogens and Catechol Amines III. Studies on the Methylation of Catechol Estrogens, Catechol Amines and other Catechols by the Catechol-O-Methyltransferase1 of Human Liver

The Journal of Clinical Endocrinology & Metabolism, 1972
The substrate specificity of the catechol-O-methyltransferase, purified from human liver 380-fold, has been tested with a variety of compounds. Catechol estrogens, as well as catechol amines are methylated to their corresponding monomethyl ethers. The relation of the rates of methylation of catechol estrogens and catechol amines depended on enzyme and ...

A semiempirical study on inhibition of catechol O-methyltransferase by substituted catechols

Journal of Computer-Aided Molecular Design, 1998
Catechol and endogenous catechol derivatives are readily methylated by catechol O-methyltransferase (COMT). In contrast, many catechol derivatives possessing electronegative substituents are potent COMT inhibitors. The X-ray structure of the active site of COMT suggests that the methylation involves a lysine as a general base.
