| 1.14.15.24 | beta-carotene + 4 reduced ferredoxin [iron-sulfur] cluster + H+ + O2 |
LUT1/CYP97C1 protein reveals a major beta-carotene hydroxylase activity in vivo when depleted in its preferred substrate alpha-carotene |
| 1.14.15.24 | beta-carotene + reduced ferredoxin [iron-sulfur] cluster + H+ + O2 |
the enzyme can convert not only the (un-substituted) beta ring but also the 4-ketolated beta-ring into the respective 3-hydroxylated groups |
