PDBe 5jxh

X-ray diffraction
2Å resolution

Structure the proprotein convertase furin in complex with meta-guanidinomethyl-Phac-RVR-Amba at 2.0 Angstrom resolution.


Function and Biology Details

Reaction catalysed:
Release of mature proteins from their proproteins by cleavage of -Arg-Xaa-Yaa-Arg-|- bonds, where Xaa can be any amino acid and Yaa is Arg or Lys. Releases albumin, complement component C3 and von Willebrand factor from their respective precursors.
