Long-chain alkyl alcohol dehydrogenase that can oxidize a broad range of alkyl alcohols from methanol to 1-triacontanol (C1 to C30) as well as 1,3-propanediol and acetaldehyde. Oxidizes isopropyl alcohol, isoamylol, acetone, octanal and decanal. The best substrate is 1-octanol. a long-chain primary fatty alcohol + H2O + 2 NAD(+) = a long-chain fatty acid + 3 H(+) + 2 NADH kcat is 136.24 sec(-1) for ethanol. kcat is 138.05 sec(-1) for acetaldehyde. kcat is 260.71 sec(-1) for 1-octanol. kcat is 518.42 sec(-1) for octanal. kcat is 283.08 sec(-1) for NAD. kcat is 4808.18 sec(-1) for NADH. kcat is 38.50 sec(-1) for NADP. Optimum pH is 8.0. Optimum temperature is 60 degrees Celsius. Homodimer. Belongs to the iron-containing alcohol dehydrogenase family. In contrast to other members of the family, it apparently does not use iron or other metals as cofactor.
