Substrates: variations in carotenoid composition found in the Rhodoplanes species might be due to modified substrate specificity of the carotenogenesis enzymes, CrtC, CrtD, and CrtF. The high content of rhodopin in Rhodoplanes cryptolactis and Rhodoplanes pokkaliisoli indicates low activity of CrtD

Substrates: The 3,4-desaturation reaction can only occur with mono-1-hydroxy carotenoids at a psi-end group or with 1,1'-dihydroxy derivatives carrying a 3',4'-double bond. 1-OH-zeta-carotene can also be converted by the desaturase. 1-OH-neurosporene is preferred over 1-OH-lycopene. No substrates are 1'-hydroxydemethylspheroidene, 1-methoxyneurosporene, 1,1'-dihydroxylycopene
