Phosphatidyl ethanolamine methyltransferase
From Wikipedia, the free encyclopedia
Phosphatidyl ethanolamine methyltransferase also known as PEMT is an enzyme which in humans is encoded by the PEMT gene.[1][2][3]
Function
The PEMT enzyme converts phosphatidylethanolamine to phosphatidylcholine by sequential methylation in the liver. The protein localizes to the endoplasmic reticulum and mitochondria-associated membranes. The gene is within the Smith-Magenis syndrome region on chromosome 17.[3]
