Chapter 16, Problem 9P

Interpretation Introduction

To Determine:

Number of residues of a coiled-coil structure are needed to span $14\text{ nm }$should be calculated.

Introduction:

Myosin is the major compound of muscle thick filaments which consists of six polypeptides. These six peptides include two heavy chains and two pair of light chains. Heavy chains have a globular terminal myosin head which is joined to a helical carboxy-terminal segments which are known as the tails. The tails are tangled to form left handed coiled coil which has a diameter about $\text{2 nm}$and $\text{130-150 nm }$long.
