IUBMB Enzyme Nomenclature


Accepted name: long-chain alkane monooxygenase

Reaction: a long-chain alkane + FMNH2 + O2 = a long-chain primary alcohol + FMN + H2O

Systematic name: long-chain-alkane,FMNH2:oxygen oxidoreductase

Comments: The enzyme, characterized from the bacterium Geobacillus thermodenitrificans NG80-2, is capable of converting alkanes ranging from C15 to C36 into their corresponding primary alcohols [1,2]. The FMNH2 cofactor is provided by an FMN reductase [3].
