Figure 1.
Figure 1. Ribbon drawing of the T. acidophilum precorrin-8x methylmutase. Secondary structure elements are colored from N- to C-terminus, blue to red.
Figure 2.
Figure 2. C superposition of the T. acidophilum structure and P. denitrificans precorrin-8x methylmutase with product bound. For simplicity, only the A/D dimer is shown, and C positions numbered for polypeptide A (colored blue). In the view shown, the 2-fold axis is horizontal. The Pa2905 dimer (the biologically relevant oligomerization state) is colored tan. The active site is formed by the dimer interface, as evidenced by the bound precorrin product hydrogenobyrinic acid (HBA) colored yellow, with nitrogens colored blue, and oxygens red. The Pa2905 dimer was generated by crystallographic 2-fold symmetry. For clarity, only HBA observed in the asymmetric unit is shown.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
