                <details>PDBEntryID_givenInChain. Protocol: Each chain was fit as a separate rigid body. X-ray coordinates for the bovine alpha3 beta3 and gamma sub-assemblies were manually fitted into the EM density using the program O. The program EMfit (Rossmann et al., 2001) was then used in order to obtain a more quantitative fit.</details>
