Figure 5.
Figure 5 (a) View of the Arg22 contacts for L22R mDHFR. Drawn with LIGPLOT (Wallace et al., 1995[236] [Wallace, A. C., Laskowski, R. A. & Thornton, J. M. (1995). Protein Eng. 8, 127-134.]-[237][bluearr.gif] ). (b) View of the contacts to MTX for L22R mDHFR-MTX-NADPH complex. Note: Glu30 makes a hydrogen-bonding contact to MTX N1 and N2 that is not shown in this projection. Drawn with LIGPLOT (Wallace et al., 1995[238] [Wallace, A. C., Laskowski, R. A. & Thornton, J. M. (1995). Protein Eng. 8, 127-134.]-[239][bluearr.gif] ).
