What is the function of sperm lysins?

Explanation

**Step-by-Step Solution:**

1. **Definition of Sperm Lysins**: Sperm lysins are enzymes that play a crucial role in the process of mammalian fertilization. They are specifically involved in breaking down barriers that prevent sperm from reaching the egg.

2. **Types of Sperm Lysins**: There are two main types of enzymes classified as sperm lysins:
- **Hyaluronidase**: This enzyme is responsible for depolymerizing hyaluronic acid, which is a component of the extracellular matrix surrounding the egg.
- **Acrosine**: This is a proteolytic enzyme that digests proteins in the structural elements of the tissue cells that are still attached to the ovum.
