Serine racemase

Serine racemase is an enzyme in the brain that converts the amino acid L-serine into its mirror-image form, D-serine. D-serine plays a crucial role as a signaling molecule, especially involved in activating certain brain receptors called NMDA receptors, which are vital for learning, memory, and neural communication. By producing D-serine, serine racemase helps regulate these important processes. It operates primarily in neurons and glial cells, ensuring balanced levels of D-serine for healthy brain function.
