Structure of PCPE-2 in complex with the BMP-1 metalloprotease reveals the molecular basis of its mechanism of inhibition
PCPE-2 (procollagen C-proteinase enhancer-2) is an extracellular glycoprotein playing dual functions in the regulation of BMP-1/tolloid-like proteinases. Like its homologue PCPE-1, PCPE-2 can enhance the proteolytic maturation of fibrillar procollagens, but it also acts as a potent and specific inhibitor of BMP-1 throu...
