A method for acylating peptides and proteins with the CoA-ester of diheteroatom substituted C.sub.13 to C.sub.14 myristic acid analogs catalyzed by N-myristoyltransferase is presented. In the analogs, two non-adjacent methylene groups, which are normally at positions 3-13, are replaced with oxygen or sulfur atoms.
Novel diheteroatom-substituted fatty acid analog substrates of myristoylating enzymes are provided which contain oxyen and/or sulfur in place of two methylene groups in carbon positions from 3 to 13 in the fatty acid chain of a C.sub.13 -C.sub.14 fatty acid analog or alkyl ester thereof in which said oxygen or sulfur atoms are separated by at least one methylene group.
