Long-Chain Alkane Monooxygenase

Ribbon diagram of the LadA dimer.

A flavoprotein alkane monooxygenase native to Geobacillus thermodinitrificans NG-80-2. It has been found to specifically oxidize the terminal regions of alkanes ranging from C15 up to at least C36. The product is the corresponding primary alkanol. LadA forms a catalytic complex with flavin mononucleotide (FMN) which utilizes dioxygen to insert an oxygen atom into the substrate.

The general catalytic function involves three chemical processes:

• Reduction of the cofactor flavin mononucleotide (FMN to FMNH2) by NAD(P)H
• Reaction of FMNH2 with O2
• Binding, orienting, and activating the substrate for its oxygenation

LadA's ability to preferentially capture long-chain alkanes for oxidation sets it apart from other flavoprotein monooxygenases[1].
