Crystal structure of a glmS ribozyme triple mutant magnesium complex (Protein Data Bank code: 4meg; Lau MW, Ferré-D’Amaré AR. 2013. An in vitro evolved glmS ribozyme has the wild-type fold but loses coenzyme dependence. Nat Chem Biol 9: 805–810). Image details show glmS ribozyme triple mutant, ribbon plate representation, substrate strand—violet, ribozyme—green; magnesium ions—spacefilling representation—yellow.
