The murine monoclonal antibody 26-2F neutralizes the angiogenic and, ribonucleolytic activities of human angiogenin (ANG) and is highly, effective in preventing the establishment and metastatic dissemination of, human tumors in athymic mice. Here we report a 2.0 A resolution crystal, structure for the complex of ANG with the Fab fragment of 26-2F that, reveals the detailed interactions between ANG and the, complementarity-determining regions (CDRs) of the antibody. Surprisingly, Fab binding induces a dramatic conformational change in the cell binding, region of ANG at the opposite end of the molecule from the combining site;, crosslinking experiments indicate that this rearrangement also occurs in, solution. The ANG-Fab complex structure should be invaluable for designing, maximally . | The murine monoclonal antibody 26-2F neutralizes the angiogenic and, ribonucleolytic activities of human angiogenin (ANG) and is highly, effective in preventing the establishment and metastatic dissemination of, human tumors in athymic mice.
