Mapping of structural elements to a region of the Ras family HMM Logo. The mapping was obtained by aligning the sequence of p21 ras, the structure of which has been solved, to the Ras family pHMM. Below the logo, insert regions are highlighted by vertical arrows, and the secondary structure of p21 ras is indicated (alpha helices: barrels; beta sheets: horizontal arrows).
