A minimum of 9 base pairs can be changed using 3 zinc fingers.

One zinc finger can bind about 3 base pairs by itself.

These zinc fingers are thought to be involved in protein-protein interactions.

Zinc fingers are much more difficult to make.

These zinc fingers can be found in several transcription factors including the yeast Gal4 protein.

The residues marked 'x' are not part of the zinc fingers, but rather serve to connect them all together.

Additionally, zinc fingers have become extremely useful in various therapeutic and research capacities.

Their secondary and tertiary structure is distinct from that of classic zinc fingers.

'Zinc finger' is the name of many protein structures.

In these two types of enzymes, the C-terminal domain forms a zinc finger.
