Structure of soybean β-cyanoalanine synthase and the molecular basis for cyanide detoxification in plants.
Plants produce cyanide (CN-) during ethylene biosynthesis in the mitochondria and require β-cyanoalanine synthase (CAS) for CN- detoxification. Recent studies show that CAS is a member of the β-substituted alanine synthase (BSAS) family, which also includes the Cys biosynthesis enzyme O-acetylserine sulfhydrylase (OASS), but how the BSAS evolved distinct metabolic functions is not understood. H...
متن کاملβ-Cyanoalanine Synthases and Their Possible Role in Pierid Host Plant Adaptation †
Cyanide is generated in larvae of the glucosinolate-specialist Pieris rapae (Lepidoptera:Pieridae) upon ingestion of plant material containing phenylalanine-derived glucosinolates as chemical defenses. As these glucosinolates were widespread within ancient Brassicales, the ability to detoxify cyanide may therefore have been essential for the host plant shift of Pierid species from Fabales to Br...
متن کاملStructure of Soybean b-Cyanoalanine Synthase and the Molecular Basis for Cyanide Detoxification in Plants
Plants produce cyanide (CN2) during ethylene biosynthesis in the mitochondria and require b-cyanoalanine synthase (CAS) for CN2 detoxification. Recent studies show that CAS is a member of the b-substituted alanine synthase (BSAS) family, which also includes the Cys biosynthesis enzyme O-acetylserine sulfhydrylase (OASS), but how the BSAS evolved distinct metabolic functions is not understood. H...
متن کاملThe Genome of Pieris rapae Granulovirus.
Pieris rapae granulovirus (PrGV) can infect and kill larvae of Pieris rapae, a worldwide and important pest of mustard family crops. The PrGV genome consists of 108,592 bp, is AT rich (66.8%), and is most structurally and organizationally similar to the Choristoneura occidentalis granulovirus genome. Of the predicted 120 open reading frames (ORFs), 32 genes specifically occurred in GVs, includi...
متن کاملCorrection: Morphological Clines and Weak Drift along an Urbanization Gradient in the Butterfly, Pieris rapae
Urban areas are increasing globally, providing opportunities for biodiversity researchers to study the process in which species become established in novel, highly disturbed habitats. This ecological process can be understood through analyses of morphological and genetic variation, which can shed light on patterns of neutral and adaptive evolution. Previous studies have shown that urban populat...
