Acyl transferase
Acyltransferases are enzymes that contain an acyl group , e.g. B. transferred an acetic acid residue or a fatty acid to a suitable acceptor. These enzymes are transferases of the EC sub-category 2.3, because they transfer the acyl residue from a donor to an acceptor. The replacement of a certain hydrogen atom of the acceptor by an acyl radical is called acylation .
Many acylations involve proteins as acceptors. Acyl-coenzyme A often serves as a donor for the acyl group and for the acylation energy .
Acyltransferases, which transfer an acetic acid residue ( acetyl residue ) to suitable acceptors, can be referred to as acetyltransferases .
