Structural Biology Plant Hormone Modulators

The activity and stability of several plant hormones are modulated by conjugation with various amino acids and their derivatives. Westfall et al. solved the crystal structures for two acyl acid amido synthetases from Arabidopsis. The findings suggest how the enzymes might discriminate between apolar and acidic amino acids and lend insight into the reaction chemistries that add functional diversity to hormone signaling pathways.
