Figure 1From: Identification of white campion (Silene latifolia) guaiacol O-methyltransferase involved in the biosynthesis of veratrole, a key volatile for pollinator attractionPurification of SlGOMT1 and SlGOMT2. Both GOMT1 and GOMT2 were purified by Ni2+ affinity chromatography and separated by SDS-PAGE. Lane 1 shows the soluble crude bacterial extract (~10 μg) and lane 2 shows the purified protein (~1 μg). Molecular weight markers are shown on the left.Back to article page
