Function
COPDA_ARATH Oligopeptidase that may be involved in the degradation of proteasome-generated peptides (By similarity). Binds salicylic acid.[1] [2]
Publication Abstract from PubMed
Thimet oligopeptidase (TOP) is a zinc-dependent metallopeptidase. Recent studies suggest that Arabidopsis thaliana TOP1 and TOP2 are targets for salicylic acid (SA) binding and participate in SA-mediated plant innate immunity. The crystal structure of A. thaliana TOP2 has been determined at 3.0 A resolution. Comparisons to the structure of human TOP revealed good overall structural conservation, especially in the active-site region, despite their weak sequence conservation. The protein sample was incubated with the photo-activated SA analog 4-azido-SA and exposed to UV irradiation before crystallization. However, there was no conclusive evidence for the binding of SA based on the X-ray diffraction data. Further studies are needed to elucidate the molecular mechanism of how SA regulates the activity of A. thaliana TOP1 and TOP2.
