TYROSINE HYDROXYLASE CATALYTIC AND TETRAMERIZATION DOMAINS FROM RAT
Overview
Tyrosine hydroxylase (TyrOH) catalyzes the conversion of tyrosine to, L-DOPA, the rate-limiting step in the biosynthesis of the catecholamines, dopamine, adrenaline, and noradrenaline. TyrOH is highly homologous in, terms of both protein sequence and catalytic mechanism to phenylalanine, hydroxylase (PheOH) and tryptophan hydroxylase (TrpOH). The crystal, structure of the catalytic and tetramerization domains of TyrOH reveals a, novel alpha-helical basket holding the catalytic iron and a 40 A long, anti-parallel coiled coil which forms the core of the tetramer. The, catalytic iron is located 10 A below the enzyme surface in a 17 A deep, active site pocket and is coordinated by the conserved residues His 331, His 336 and Glu 376. The structure provides a rationale for the effect of, point ... [(full description)]
