From which microbe is streptokinase produced and what is its role?

Explanation

**Step-by-Step Solution:**

1. **Identify the Microbe**: Streptokinase is produced by a specific type of bacteria known as *Streptococcus*. More specifically, it is produced by *Streptococcus pyogenes*, which is a beta-hemolytic strain of this genus.

2. **Understand the Role of Streptokinase**: The primary role of streptokinase is to facilitate thrombolysis, which is the process of breaking down blood clots. This is particularly important in medical situations where blood clots can obstruct blood flow, such as during a heart attack or stroke.

3. **Mechanism of Action**: Streptokinase acts by converting plasminogen, a plasma protein, into plasmin, which is an enzyme that dissolves fibrin clots. This action helps restore normal blood flow in blocked vessels.
