How do Sulfurylase and Luciferase contribute to DNA sequencing in pyrosequencing?

Sulfurylase generates ATP from pyrophosphate, and Luciferase uses ATP to emit light.

Sulfurylase enhances DNA polymerase activity, and Luciferase stabilizes DNA strands.

Sulfurylase breaks down DNA strands, and Luciferase labels them with fluorescent tags.

Sulfurylase converts pyrophosphate to protons, and Luciferase detects pH changes.
