Figure 2.
Fig. 2. a: Omit (Fo−Fc) map around a portion of the N-terminal helix including the catalytic His12. b: Omit (Fo−Fc) electron density around the hinge loop of one of the two subunits in the M=M crystal structure. Residues Ser20 and Ser21, which are fully disordered, are modeled (light gray) to show the hinge connectivity. c: Stereo diagram showing the hinge region after the superposition of a subunit of M=M (dark gray) with RNase A (medium gray) and hRNase (light gray).
