  ABSTRACT  
 
Procollagen C-peptidase, also known as bone morphogenetic protein 1 (BMP-1), is a multidomain, zinc endopeptidase of the astacin M12A family. BMP-1 is the prototype of a small group of proteases that have key roles in extracellular matrix formation and morphogenesis. BMP-1, its splice form mTLD, and the related proteases TLL-1 and TLL-2 are considered as promising drug targets for the treatment of excessive fibrosis and muscle wasting. We report here the crystal structures of the protease domains of human BMP-1 and the closely related Tolloid-like protease 1 (TLL-1). The crystal structures reveal an unexpected conformation of a cysteine-rich loop within the active site, and suggest that a flap movement is required in order to allow substrate binding. On the basis of these substantial differences between the BMP-1 and astacin active sites, a structural basis for their differing substrate specificities is proposed.

(b) The concentration of free inhibitor plotted against increasing amounts of BMP-1. The concentration dependence of the observed reduction in peak intensity indicates a 1:1 binding event.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
