Tyrosine hydroxylase, the rate limiting enzyme in the biosynthesis of catecholamine, is a tetramer composed of four subunits of the same molecular mass. A full length cDNA clone encoding tyrosine hydroxylase has been inserted into the SP6 expression system. Translation of the corresponding RNA in Xenopus oocyte results in enzymatic activity, demonstrating that a single gene contains all the necessary genetic information to code for a functional enzyme. The potential of this system in the analysis of posttranslational tyrosine hydroxylase modifications is discussed.
