Here, we describe the crystal structure of Caenorhabditis elegans PRMT7 in complex with its reaction product S-adenosyl-l-homocysteine. The structural data indicated that PRMT7 harbors two tandem repeated PRMT core domains that form a novel homodimer-like structure. S-adenosyl-l-homocysteine bound to the N-terminal catalytic site only; the C-terminal catalytic site is occupied by a loop that inhibits cofactor binding. Mutagenesis demonstrated that only the N-terminal catalytic site of PRMT7 is responsible for cofactor binding. Protein arginine methyltransferase 7 has a novel homodimer-like structure formed by tandem repeats.,Hasegawa M, Toma-Fukai S, Kim JD, Fukamizu A, Shimizu T FEBS Lett. 2014 Apr 9. pii: S0014-5793(14)00272-5. doi:, 10.1016/j.febslet.2014.03.053.
