Human Transthyretin (TTR) complexed with genistein

Introduction

Human Transthyretin (TTR) is a gene that provides instructions for the producing of a protein called transthyretin. Transthyretin is composed of identical 127-aa sandwich subunits (shown in pink) that are produced primarily in the liver.

Overall Structure

Human transthyretin (TTR) is a 55 kDa homotetramer (or more precisely, a dimer of dimers) that transports thyroxine and retinol-binding protein in the blood and cerebrospinal fluid. The monomer consists of two four-stranded β􏰆-sheets, arranged in a tertiary structure.

As you can see, there are a total of five interactions. The Hydrogen Bonds are colored blue, and the hydrophobic interactions are colored pink. The orange color is where both hydrogen bonding and hydrophobic interactions occur at the same time.

TTR has two identical thyroxine-binding sites located at the dimer-dimer interface. Locate them. It is the blue, green or grey/red structures?
