Mouse Beta Carotene Dioxygenase

It is an oxidoreductase-enzyme which catalyzes the conversion of beta-carotene to retinal in the presence of oxygen, according to the reaction:
beta-carotene + O2 <=> 2 retinal.
The product of this enzymatic reaction, i.e Retinal is a VitaminA aldehyde. It is a polyene chromophore which binds to proteins called 'Opsins' (say Proteorhodopsin). This retinal-opsin complex allows microorganisms to convert light energy to metabolic energy. Hence in micro-organisms functionally expressing Proteorhodopsin, beta-carotene dioxygenase converts beta-carotene to Trans-retinal, which is required for the functioning of Proteorhodopsin.
