From: APOBEC3H structure reveals an unusual mechanism of interaction with duplex RNA
Crystal structure of pgtA3Hζ-RNA complex. a Two A3H molecules (blue and green cartoon, Zn as gray sphere) at the ends of a central RNA duplex (orange backbone, yellow bases). b Sites of pgtA3H polymorphic variation. The A3H surface (colored as in A) with sites of variation in magenta. The RNA is nearly engulfed by the two A3H molecules, which have no direct contacts with each other
