CRYSTAL STRUCTURE OF RAT GTP CYCLOHYDROLASE I FEEDBACK REGULATORY PROTEIN, GFRP


Overview

Tetrahydrobiopterin, the cofactor required for hydroxylation of aromatic amino acids regulates its own synthesis in mammals through feedback inhibition of GTP cyclohydrolase I. This mechanism is mediated by a regulatory subunit called GTP cyclohydrolase I feedback regulatory protein (GFRP). The 2.6 A resolution crystal structure of rat GFRP shows that the protein forms a pentamer. This indicates a model for the interaction of mammalian GTP cyclohydrolase I with its regulator, GFRP. Kinetic investigations of human GTP cyclohydrolase I in complex with rat and human GFRP showed similar regulatory effects of both GFRP proteins.
