Function
CRTDH_NONDD Catalyzes the introduction of a C-3,4 double bond into 1'-hydroxy-gamma-carotene and rhodopin (1-hydroxylycopene) to yield 1'-hydroxytorulene and (3E)-3,4-didehydrorhodopin, respectively (By similarity). Can also use 1-hydroxy-all-trans-1,2-dihydro-neurosporene, 1,1'-dihydroxy-1,1',2,2'-tetrahydroneurosporene and 1,1'-dihydroxy-1,1',2,2'-tetrahydrolycopene (By similarity). Probably involved in the synthesis of myxol, a gamma-carotene derivative (Probable). May use FAD as a proton acceptor (Probable).[UniProtKB:Q7WT72][1]
