DNase footprinting gives a good idea of the location of the binding site for the protein, but DNase is a macromolecule and is therefore a rather blunt instrument for probing the fine details of the binding site.

THERMAL PROPERTIES OF WATER

Pure water becomes a solid below 0°C and becomes a gas above 100°C at sea level.

When water contains dissolved compounds, such as salts, its freezing temperature drops below 0°C.

Dissolved compounds also raise the boiling point of water above 100°C.

M6P residues are generated in the cis-Golgi by two Golgi-resident enzymes. 

1. N-acetylglucosamine (GlcNAc) phosphotransferase
2. Phosphodiesterase
