Component of the propane 2-monooxygenase multicomponent enzyme system which is involved in the degradation of propane via the O2-dependent hydroxylation of propane (PubMed:14645271). Under acetone induction, also able to catalyze the oxidation of phenol to yield hydroquinone (PubMed:21183637). H(+) + NADH + O2 + propane = H2O + NAD(+) + propan-2-ol H(+) + NADH + O2 + phenol = H2O + hydroquinone + NAD(+) Binds 2 Fe(2+) ions per subunit. The propane 2-monooxygenase multicomponent enzyme system is composed of an electron transfer component and a monooxygenase component interacting with the effector protein PrmD. The electron transfer component is composed of a reductase (PrmB), and the monooxygenase component is formed by a large subunit (PrmA) and a small subunit (PrmC) (PubMed:14645271). Probably requires the presence of the chaperonin-like protein PrmG to ensure a productive folding, resulting of a soluble PrmA, which leads to the active form of PrmABCD (PubMed:23171424). By propane and acetone. Belongs to the TmoA/XamoA family.
