Activating Compound

Activating Compound Comment Organism Structure
acetone activates at lower concentration, Chlase2 reaches its maximal activity in 40% acetone, in 40-60% acetone the activity is reduced, overview Arabidopsis thaliana

Cloned(Commentary)

Cloned (Comment) Organism
gene chl2, expression anaylsis, recombinant expression in Escherichia coli strain BL21 (DE3) Arabidopsis thaliana

Protein Variants

Protein Variants Comment Organism
additional information inhibition of expression of AtCLH2 by RNA interference, transfection using Agrobacterium tumefaciens strain LBA4404, AtCLH2 RNAi plants show decreased contents of chlorophyllide without a substantial change in the total amount of the extractable chlorophyll and consequently presented lower chlorophyllide to chlorophyll ratios in their leaves, phenotype, overview Arabidopsis thaliana
