Qu'est-ce (qui) est ZZ zinc finger - définition
Zinc finger nuclease
CLASS OF ARTIFICIAL ENZYMES
Zinc finger nucleases; Zinc finger protein nucleases; Zinc-finger nuclease; Nucleasas con dedos de zinc; ZFNs
Zinc-finger nucleases (ZFNs) are artificial restriction enzymes generated by fusing a zinc finger DNA-binding domain to a DNA-cleavage domain. Zinc finger domains can be engineered to target specific desired DNA sequences and this enables zinc-finger nucleases to target unique sequences within complex genomes.
ZZ zinc finger
In molecular biology the ZZ-type zinc finger domain is a type of protein domain that was named because of its ability to bind two zinc ions. These domains contain 4-6 Cys residues that participate in zinc binding (plus additional Ser/His residues), including a Cys-X2-Cys motif found in other zinc finger domains.
PHD finger
PROTEIN SEQUENCE
Plant homeodomain finger; Plant homeodomain; PHD-type zinc finger
The PHD finger was discovered in 1993 as a Cys4-His-Cys3 motif in the plant homeodomain (hence PHD) proteins HAT3.1 in Arabidopsis and maize ZmHox1a.
