REACTIONS OF 4-METHYL-o-BENZOQUINONE, GENERATED CHEMICALLY OR ENZYMATICALLY, IN THE PRESENCE OF L-PROLINE

Article abstract of DOI:10.1016/0031-9422(88)80096-7

The reactions of 4-methyl-o-benzoquinone in the presence of L- proline were studied by rapid scanning spectrophotometry.It was concluded that it was transformed into 5-methyl-4-N-prolyl-o-benzoquinone, according to the equation: 2(4-methyl-o-benzoquinone) + L-proline->4-methylcatechol + 5-methyl-4-N-prolyl-o-benzoquinone.Rate constants for the reaction of 4-methyl-o-benzoquinone with water and L-proline have been measured.Key Word Index-Tyrosinase; 4-methylcatechol; 4-methyl-o-benzoquinone; L-proline.
