MolRep: Antibodies (I)<br />

Antibodies can help with crystallizati<strong>on</strong> of soluble proteins,<br />

RNA and membrane proteins (by making rigid crystal packing<br />

c<strong>on</strong>tacts)<br />

Once crystallized antibodies can be placed in <strong>the</strong> unit cell by<br />

molecular replacement and will provide phasing informati<strong>on</strong><br />

about <strong>the</strong> studied molecule (RNA, membrane protein, etc)<br />

855 models of antibody are deposited in <strong>the</strong> Protein Data<br />

Bank. Due to hinge variability it is difficult to predict which<br />

antibody molecule will provide a clear molecular replacement<br />
