RG1_RAUSE Glucosidase specifically involved in alkaloid biosynthesis leading to the accumulation of several alkaloids, including ajmaline, an important plant-derived pharmaceutical used in the treatment of heart disorders.[1]
Publication Abstract from PubMed
X-ray measurements at room temperature (295K) deliver high quality data sets with unprecedented speed (<2min), as shown for crystallized raucaffricine-O-beta-d-glucosidase (RG), its mutant RG-Glu186Gln and several ligand complexes of the enzyme which participates in alkaloid biosynthesis in the plant Rauvolfia. The data obtained are compared with data sets measured under typical cryo conditions (100K). Under both conditions, density maps are highly comparable and favor the described protocol for room temperature measurements, potentially paving the way for future crystallographic studies capturing biosynthetic pathway intermediates.
