Crystal structure of human tryptophan hydroxylase with bound 7,8-dihydro-L-biopterin cofactor and Fe(III)
Contents |
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.
