COMMENTARY 
LITERATURE
A447S
like the wild-type enzyme the mutant enzyme adds two epsilon-rings to lycopene, forming epsilon-carotene
L448H
the mutant adds two epsilon-ring to lycopene, forming epsilon-carotene
L448R
the mutant adds two epsilon-ring to lycopene, forming epsilon-carotene
down
H457D
the mutant enzyme forms a higher amount of ratio delta-carotene compared to the wild-type enzyme
H457L
the mutant adds only one epsilon-ring to lycopene, forming delta-carotene
H457R
like the wild-type enzyme the mutant enzyme predominantly form epsilon-carotene (91%)

additional information
down
the shift from the beta,epsilon-branch to the beta,beta-branch of the pathway that originates the changes in carotenoid composition during fruit coloration may be explained by a down-regulation of epsilon-LCY and by the increase of the beta-CHX transcript

for production of lutein in tomato fruits, it is required to overcome the enzyme downregulation before fruit ripening exhibited through a tightly regulated physiological mechanism in tomato fruits by overexpression of lycopene epsilon- and beta-cyclases in leaves and ripe fruits, carotene profile and contents, overview
