1O8R - PubMed Abstract: 
The endogenous ligand of guanylyl cyclase C, guanylin, is produced as the 94-amino-acid prohormone proguanylin, with the hormone guanylin located at the COOH terminus of the prohormone. The solution structure of proguanylin adopts a new protein fold and consists of a three-helix bundle, a small three-stranded beta-sheet of two NH2-terminal strands and one COOH-terminal strand, and an unstructured linker region ...
