Cloned(Commentary)

Cloned (Comment) Organism
prmt6 is cloned in the pnEA-vHis vector between the NdeI and XhoI restriction sites and used to transform Escherichia coli BL21 (DE3) pRARE2 cells. The resulting recombinant protein harbors an amino-terminal hexahistidine tag followed by a Tobacco etch virus (TEV) protease cleavage site. The protein also contains a F315L point mutation, reported for the entry as a natural variant Mus musculus

Crystallization (Commentary)

Crystallization (Comment) Organism
sitting-drop vapor-diffusion method at 20°C. Six crystal structures of PRMT6 are solved and refined at 1.34 A for the highest resolution structure.The crystal structures reveal that the folding of the helix aX is required to stabilize a productive active site before methylation of the bound peptide can occur. In the absence of cofactor, metal cations can be found in the catalytic pocket at the expected position of the guanidinium moiety of the target arginine substrate Mus musculus
