1.14.15.3 | additional information | AbAlkB can catalyze the hydroxylation of a large number of aromatic compounds and linear and cyclic alkanes. It does not catalyze the hydroxylation of alkanes with a chain length longer than 15 carbons, nor does it hydroxylate sterically hindered C-H bonds. GC-MS product analysis, overview. AbAlkB hydroxylates the terminal methyl group of medium chain alkanes, where octane is apparently close to the optimal chain length | Alcanivorax borkumensis | ? | - |

1.14.15.3 | norcarane + reduced rubredoxin + O2 | i.e. bicyclo[4.1.0]heptane, oxidation preferentially occurs at the less sterically hindered 3-position, reaction via formation of a substrate radical that persists in the active site | Alcanivorax borkumensis | ? + oxidized rubredoxin + H2O | - |

1.14.15.3 | additional information | reconstitution of enzyme activity with the purified protein in an assay with purified rubredoxin, purified maize ferredoxin reductase, NADPH, and selected substrates. i.e. bicyclo[4.1.0]heptane (norcarane), bicyclo[3.1.0]hexane (bicyclohexane), methylphenylcyclopropane and deuterated and non-deuterated cyclohexane. Purified AbAlkB hydroxylates substrates by forming a substrate radical, the rate-determining step has a significant C-H bond breaking character | Alcanivorax borkumensis |
