Figure 3. The 1D
1
H-NMR spec-
tra of the (a) parent Zn finger and
(b) variant Zn finger at 500 MHz
and 25 °C. Asterisks in (b) indicate
upfield methyl resonances of L10.
The upfield region of the wild-type
spectrum is remarkable for the
b-methylene protons of K25
(labeled in (a)). Arrow indicates
down-field amide resonance of
Y7, a characteristic feature of Zn
fingers.
