| 5.5.1.18 | metabolism |
the cyclation of lycopene into either alpha- or beta-carotene is a key branch point in the pathway of carotenoid biosynthesis in plants and some algal classes and has been proposed as a control step, the relative activities of LCYe and LCYb determine the proportion of carotenoids directed to each branch of the pathway, overview |
