Acyl-CoA mutases are a growing class of adenosylcobalamin-dependent radical enzymes that perform challenging carbon skeleton rearrangements in primary and secondary metabolism. Members of this class of enzymes must precisely control substrate positioning to prevent oxidative interception of radical intermediates during

According to the concept presented, esters forming an amide (peptide) bond by the mechanism SN#DN or SN#*DN involving fast decay of the tetrahedral intermediate may behave as 'superactive acylating reagents'. These should render coupling involving less reactive substrates, i.e. sterically
