Structural comparison of the C-terminal globular domain of Archaeoglobus fulgidus AglB-L with other archaeal and eubacterial structures. (A) A. fulgidus AglB-L, (B) A. fulgidus AglB-S1, (C) A. fulgidus AglB-S2, (D) Campylobacter jejuni PglB, (E) Pyrococcus furiosus AglB-L, and (F) Pyrococcus horikoshii AglB-L. The domain organization is shown: TM, transmembrane; CC, central core; IS, insertion; P1, peripheral 1; P2, peripheral 2. The TM region, which was not included in the structure determination, is outlined in gray. The CC unit is colored blue, IS is green, P1 is yellow, and P2 is red. The characteristic kinked helix in the CC unit is colored light brown, as a landmark for comparison.
