A Study of the Structure of Fibronectin

A Study of the Structure of Fibronectin

V E Koteliansky et al. Eur J Biochem.

Abstract

The structure of a fibronectin molecule has been studied by circular dichroism, infrared spectroscopy, scanning microcalorimetry and electron microscopy. It has been shown that the secondary structure of fibronectin is formed exclusively by the antiparallel beta-form -- 35%; the fibronectin molecule consists of several domains; the protein has a compact structure, the length of the molecule is 15.5 +/- 1.3 nm, the width is 8.8 +/- 1.7 nm, the axial ratio is approximately 2:1.1.
