4.1.99.5	additional information	the aldehyde hydrogen is retained in the HCO2- and the hydrogen in the nascent methyl group of the alkane originates, at least in part, from solvent. The reaction appears to be formally hydrolytic, but the improbability of a hydrolytic mechanism having the primary carbanion as the leaving group, the structural similarity of the aldehyde decarbonylases to other O2-activating non-heme di-iron proteins, and the dependence of in vitro aldehyde decarbonylase activity on the presence of a reducing system implicate some type of redox mechanism. Two possible resolutions to this conundrum, overview
