Production and crystallization of the C‐propeptide trimer from human procollagen III

Production and crystallization of the C‐propeptide trimer from human procollagen III The C‐propeptide domains of the fibrillar procollagens, which are present throughout the Metazoa in the form of ∼90 kDa trimers, play crucial roles in both intracellular molecular assembly and extracellular formation of collagen fibrils. The first crystallization of a C‐propeptide domain, that from human procollagen III, is described. Following transient expression in mammalian 293T cells of both the native protein and a selenomethionine derivative, two crystal forms of the homotrimer were obtained: an orthorhombic form (P212121) that diffracted to 1.7 Å resolution and a trigonal form (P321) that diffracted to 3.5 Å resolution. Characterization by MALDI‐TOF mass spectrometry allowed the efficiency of selenomethionine incorporation to be determined. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Crystallographica Section F Wiley

Abstract

The C‐propeptide domains of the fibrillar procollagens, which are present throughout the Metazoa in the form of ∼90 kDa trimers, play crucial roles in both intracellular molecular assembly and extracellular formation of collagen fibrils. The first crystallization of a C‐propeptide domain, that from human procollagen III, is described. Following transient expression in mammalian 293T cells of both the native protein and a selenomethionine derivative, two crystal forms of the homotrimer were obtained: an orthorhombic form (P212121) that diffracted to 1.7 Å resolution and a trigonal form (P321) that diffracted to 3.5 Å resolution. Characterization by MALDI‐TOF mass spectrometry allowed the efficiency of selenomethionine incorporation to be determined.
