The invention is a method of making a L-dopa from L-tyrosine in the presence of an enzyme catalyst and oxygen. By starting with L-tyrosine, no variant of the L-dopa is produced and the L-dopa is stable in the presence of the enzyme catalyst. In other words, the reaction favors the L-dopa and is not reversible.
