Problem:
I'm looking for an Arabidopsis thaliana gene listed in RCSB with a clear mode of function and active site. In addition it needs to have an obvious phenotype when knocked out like severely retarded growth, lethal or near lethal. The gene also has to be exclusive to plants so RNA polymerase wouldn't work. I found this paper in plant physiology but I'm having trouble finding those genes with an obvious active site.
If anyone knows something about it please explain.
