Mitochondrial acyltransferase which transfers an acyl group to the N-terminus of glycine and glutamine, although much less efficiently. Can conjugate numerous substrates to form a variety of N-acylglycines, with a preference for benzoyl-CoA over phenylacetyl-CoA as acyl donors. Thereby detoxify xenobiotics, such as benzoic acid or salicylic acid, and endogenous organic acids, such as isovaleric acid. an acyl-CoA + glycine = an N-acylglycine + CoA + H(+) benzoyl-CoA + glycine = CoA + H(+) + N-benzoylglycine Predominantly expressed in liver (at protein level) and kidney. Down-regulated in hepatocellular carcinoma and other liver cancers. Belongs to the glycine N-acyltransferase family. Truncated N-terminus. Truncated N-terminus.
