From: The archaeo-eukaryotic GINS proteins and the archaeal primase catalytic subunit PriS share a common domain

Figure 2

Primase CTD and GINS B-domain structures share a common fold. A. Structure of the C-terminal domain (CTD, amino acids 274-329) of the S. solfataricus PriS protein (PDB code 1ZT2, chain A) with the five conserved β-strands β1-β5 and helix α1 indicated. B. Structure of the N-terminal B-domain (amino acids 12-61) of the human GINS subunit Psf2 (PDB code 2E9X, chain B). C. Structure of the C-terminal B-domain (amino acids 167-223) of human Sld5 (PDB code 2E9X, chain D). Note the presence of an additional α-helix between β-strands β2 and β3. D. Structure of the N-terminal B-domain (amino acids 30-87) of the human Psf3 (PDB code 2E9X, chain C). Amino acids 48-56 are missing from the structure (indicated by broken line).
