Crystal structure of moCD163 SRCR5 and comparison with pCD163 SRCR5. A The cartoon diagrams of moCD163 SRCR5 represented in the 180° rotation. Seven β-strands β1-7, three helices α1-3 and the loop regions are colored in blue, magenta and cyan, respectively. The N- and C-termini are labeled. B The ribbon diagrams of moCD163 SRCR5 showing the disulfide bonds represented in the 180° rotation. The disulfide bonds are colored in yellow and the bridged cysteines are labeled. C Structural comparison of moCD163 SRCR5 with pCD163 SRCR5. The crystal structures of moCD163 SRCR5 was aligned with pCD163 SRCR5 in cartoon diagrams. The pCD163 SRCR5 and moCD163 SRCR5 are in green and cyan, respectively. Their N- and C-termini are labeled, and their minor differences are circled in dashed lines.
