GtfB-CD apo: full-length versus truncated (proteolysed). The truncated GtfB (green) crystallized in space group P212121 and diffracted to 1.48 Å resolution. The intact GtfB-CD structure is shown in light blue. Overall there is not much difference, and the structures superpose with an r.m.s.d. of 0.25 Å (for 2702 of 3749 aligned atoms). The calcium ion is presented as a pink sphere in GtfB-CD, whereas the truncated GtfB contains a magnesium ion (yellow) at a different site.
