... by scintillation counting. The incubations contained no ligand (d), 40 l M H 4 biopterin (m), 40 l M dopamine (n)or1 m M L-Phe in combination with either 40 l M H 4 biopterin or 40 l M dopamine ... [32]. Secondly, on binding at the active site, the dopamine main- chain interacts with the autoregulatory sequence at Ser23 (by hydrogen bonding) and Ile25 (Fig. 4), which results in an inh...
