Coagulase production by Staphylococcus aureus converts fibrinogen to what?

Explanation:
Coagulase from Staphylococcus aureus forms a complex with prothrombin to become staphylothrombin, which then converts soluble fibrinogen into insoluble fibrin. That fibrin forms a clot around the bacteria, helping it resist phagocytosis. So the product of this reaction is fibrin. Fibrinogen is the substrate, while fibronectin and elastin are different proteins not involved in this specific conversion.
