SSB consists is a homotetramer that has a DNA binding domain which binds to a single strand of DNA. The tetramers consist of α-helices, β-sheets, and random coils. Each subunit contains an <scene name='56/566528/Alpha_helices/3'>α-helix</scene> and several <scene name='56/566528/Beta_sheets/1'>β-sheets</scene>. The secondary structure also includes a NH2 terminus, which consists of multiple positively charged amino acids. The COOH terminus includes many acidic amino acids. | SSB consists is a homotetramer that has a DNA binding domain which binds to a single strand of DNA.
