motivos en dedos de zinc
Scope note: Motivos en las proteínas de unión a ADN y ARN cuyos aminoácidos se encuentran agrupados en una sola unidad estructural alrededor de un átomo de zinc. En el dedo de zinc clásico, hay un átomo de zinc rodeado de dos cisteínas y dos histidinas. Entre las cisteínas y las histidinas hay doce residuos que constituyen una yema de unión al ADN. Mediante variaciones en la composición de las secuencias en la yema y el número y espacio de las repeticiones en tándem del motivo, los dedos de zinc pueden formar muchos puntos de acoplamiento con secuencias específicas diferentes.

Scope note: Motifs in DNA- and RNA-binding proteins whose amino acids are folded into a single structural unit around a zinc atom. In the classic zinc finger, one zinc atom is bound to two cysteines and two histidines. In between the cysteines and histidines are 12 residues which form a DNA binding fingertip. By variations in the composition of the sequences in the fingertip and the number and spacing of tandem repeats of the motif, zinc fingers can form a large number of different sequence specific binding sites.
