17-KDA FRAGMENT OF HEDGEHOG C-TERMINAL AUTOPROCESSING DOMAIN
Overview
The approximately 25 kDa carboxy-terminal domain of Drosophila Hedgehog, protein (Hh-C) possesses an autoprocessing activity that results in an, intramolecular cleavage of full-length Hedgehog protein and covalent, attachment of a cholesterol moiety to the newly generated amino-terminal, fragment. We have identified a 17 kDa fragment of Hh-C (Hh-C17) active in, the initiation of autoprocessing and report here its crystal structure., The Hh-C17 structure comprises two homologous subdomains that appear to, have arisen from tandem duplication of a primordial gene. Residues in the, Hh-C17 active site have been identified, and their role in Hedgehog, autoprocessing probed by site-directed mutagenesis. Aspects of sequence, structure, and reaction mechanism are conserved between Hh-C17 and the, ... [(full description)]
