Synthetic ribonuclease molecule. Molecular model showing the secondary structure of amphinase,a synthetic version of a ribonuclease molecule found in the egg cells of the northern leopold frog (Rana pipiens). Ribonucleases are enzymes that break up RNA (ribonucleic acid),a molecule used to translate genes into their protein products. Amphinase attaches to glycoproteins on a cell,before invading the cell and killing it by destroying its RNA. Here the amphinase molecule is attached to NAG (N-acetyl-D-Glucosamine,ball and stick structure) a human glycoprotein. Amphinase could potentially be used as an anti-tumour drug,as tumours (especially brain tumours) are covered in glycoproteins (unlike healthy cells) | |
