Glycine-N-Acyltransferase Like Protein 2 (GLYATL2)

hGLYATL2, a member of a gene family of 4 putative glycine conjugating enzymes, and show that it synthesizes various N-acyl glycines. Recombinantly expressed hGLYATL2 efficiently conjugated oleoyl-CoA, arachidonoyl-CoA, and other medium- and long-chain acyl-CoAs to glycine. The enzyme was specific for glycine as an acceptor molecule, and preferentially produced N-oleoyl glycine. The hGLYATL2 enzyme is localized to the endoplasmic reticulum, and the mRNA shows highest expression in salivary gland and trachea, but is also detected in spinal cord and skin fibroblasts. The expression pattern and the identification of high levels of N-acyl glycines in skin and lung may indicate a role for N-acyl glycines in barrier function/immune response and the potential role of hGLYATL2 in this regard is discussed. Identification of glycine N-acyltransferase-like 2 (GLYATL2) as a transferase that produces N-acyl glycines in humans.
