In archetypal DNA binding ZFPs, such as transcription factor IIIA (TFIIIA) and GATA-binding factor 1 (GATA-1, which binds the DNA sequence GATA), we see that a beta-hairpin and an alpha-helix are folded around a Zn ion and that it is the alpha-helix that binds with the major groove of DNA

The 20 Standard Amino Acids Only 20 common or standard amino acids that are used in building proteins R group The 20 amino acids are distinguished by their R group or side chains The side chains vary in size, shape charge, hydrogen-bonding capacity, hydrophobic character and chemical reactivity These properties give rise to the various functions of a protein Classification of amino acids(according to the chemical nature) On the basis of R-group 20 common amino acids are categorized into 7 distinct groups Aliphatics amino acids : G A V L I OH grp containing amino acids (2+1): S T [Y] Sulfur containing amino acids (2): C M Acidic amino acids and Amides (2+2) : D N E Q Basic amino acids (3) : R K H Aromatic amino acids (3+1): F Y W [H ] Imino acid (1) : P 2
