The crystallographic structure of RiAFP was defined recently<ref>DOI 10.1074/jbc.M113.450973</ref>. It reveals a new β-solenoid architecture that forms <scene name='60/607864/Beta_sheets/1'>β-sandwich</scene> of <scene name='60/607864/Beta_sheets_colored/1'>two parallel 6 and 7 stranded-sheets</scene> of remarkable regularity. The β-sheets lie on top of each other with the upper and lower strands parallel but in the opposite orientation. Two ends deviate from β helix regularity by forming <scene name='60/607864/Beta_sheets_capping/2'>capping structures</scene>. These capping structures help to prevent end-to-end associations that would spoil the solubility of RiAFP and lead to oligomerization and aggregation. | The crystallographic structure of RiAFP was defined recently<ref>DOI 10.1074/jbc.M113.450973</ref>.
