Reactions of 3-ethylcatechol and 3-(methylthio)catechol with catechol dioxygenases
Archives of Biochemistry and Biophysics, 1986The reactions of 3-ethylcatechol and 3-(methylthio)catechol with catechol 1,2-dioxygenase and catechol 2,3-dioxygenase from Pseudomonas putida were examined. Both 3-substituted catechols are oxidized by catechol 2,3-dioxygenase at approximately 30% of the rate observed for catechol oxidation by this enzyme.

A semiempirical study on inhibition of catechol O-methyltransferase by substituted catechols
Journal of Computer-Aided Molecular Design, 1998Catechol 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.

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, 1993A 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.

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 ...
