Zinc finger DNA-binding domain. Illustration of a regulatory protein (blue) binding to DNA (deoxyribonucleic acid,orange helix) in a zinc finger formation. Such protein-DNA binding can enhance or suppress expression of the genetic information carried by the DNA. In this type of DNA-binding protein,an alpha helix (cylinder) and two beta sheets (arrows) are co-ordinated around a zinc ion (yellow) to form a 'zinc finger' (upper left) that binds to the DNA. The key protein component is called the 'recognition alpha helix'. For this artwork without labels,see C023/8885 | |
