Cloned(Commentary)
| EC Number | Cloned (Comment) | Organism |
|---|---|---|
| 1.14.13.122 | expression of the enzyme under control of the 35S CaMV promoter, using the Agrobacterium tumefaciens infection system, in transgenic Arabidopsis thaliana plants renders the transgenic plants capable of normal rate photosynthetic growth also under low light conditions in contrast to the wild-type Arabidopsis thaliana plants, transgenic plants show altered chlorophyll a/b ratio, chloroplast structure, and thylakoid membrane composition | Prochlorothrix hollandica |
| 1.14.13.122 | introductionof the prokaryotic chlorophyll b synthesis gene for chlorophyllide a oxygenase (CAO) into Arabidopsis. In the transgenic plants (Prochlirothrix hollandica CAO plants), about 40% of chlorophyll a of the core antenna complexes is replaced by chlorophyll b in both photosystems | Prochlorothrix hollandica |
