A line graph compares the evolutionary rates of three proteins-fibrinopeptides (very fast), hemoglobin (intermediate), and cytochrome c (slow)-by showing amino acid changes per 100 residues over millions of years since divergence from a common ancestor, with geological time periods and major organism groups labeled along the axes.

Quick Summary

A line graph compares the evolutionary rates of three proteins-fibrinopeptides (very fast), hemoglobin (intermediate), and cytochrome c (slow)-by showing amino acid changes per 100 residues over millions of years since divergence from a common ancestor, with geological time periods and major organism groups labeled along the axes.
evolutionary rates in proteins Three proteins with very different evolutionary rates: fibrinopeptides (very fast), hemoglobin (intermediate), and cytochrome c (slow).

Fibrinopeptides are small polypeptides released from fibrinogen by the enzyme thrombin during the process of blood clot formation.12

Fibrinogen is a protein found in blood plasma that converts into insoluble fibrin when a clot forms. Thrombin catalyzes the breakage of peptide bonds in fibrinogen, releasing fibrinopeptides. The remaining fibrinogen molecules then form a stable, insoluble fibrin clot. This process is essential for stopping bleeding and is dependent on calcium ions.2
