Crystal structure of human tryptophan hydroxylase with bound 7,8-dihydro-L-biopterin cofactor and Fe(III)
Overview
Tryptophan hydroxylase oxidizes L-tryptophan to 5-hydroxy-L-tryptophan in the rate-determining step of serotonin biosynthesis. We have determined the X-ray crystal structure (1.7 A) of a truncated functional form of human tryptophan hydroxylase with the bound cofactor analogue 7,8-dihydro-L-biopterin, providing the first atomic-resolution information for the catalytic domain of this important enzyme. Comparison of the three-dimensional structures of all three members of the aromatic amino acid hydroxylase family--tyrosine hydroxylase, phenylalanine hydroxylase, and tryptophan hydroxylase--reveals important differences at the active sites.
