Methanotrophs,in Contrast to Non-Methanotrophic Methylotrophs,may Contain This Enzyme

Question

Methanotrophs,in contrast to non-methanotrophic methylotrophs,may contain this enzyme.
A)methane carboxylase
B)methane lyase
C)methane monooxygenase
D)methane dehydrogenase
E)methane kinase

Accepted Answer

Methanotrophs are bacteria that are capable of utilizing methane as their sole source of energy and carbon. Methane monooxygenase (MMO) is a key enzyme in the oxidation of methane to methanol by methanotrophs. It is not present in non-methanotrophic methylotrophs, which use other compounds like methanol, formaldehyde, and methylamine as a source of carbon and energy. Therefore, option C (methane monooxygenase) is the best choice.
