Introduction Molecular graphics still plays an important role in the deter- mination of protein structures using X-ray crystallographic data, despite on-going efforts to automate model building. Functions such as side-chain placement, loop, ligand and fragment ®tting, structure comparison, analysis and validation are routinely performed using molecular graphics. Lower resolution (d worse than 2.5 A) data in particular need min interactive ®tting. The introduction of FRODO (Jones, 1978) and then O (Jones et al., 1991) to the ®eld of protein crystallography was in each case revolutionary, each in their time breaking new ground in demonstrating what was possible with the current hardware. These tools allowed protein crystallographers to enjoy what is widely held to be the most thrilling part of their TI - Coot: model-building tools for molecular graphics JF - Acta Crystallographica Section D Biological Crystallography DO - 10.1107/s0907444904019158 DA - 2004-11-26 UR - https://www.deepdyve.com/lp/unpaywall/coot-model-building-tools-for-molecular-graphics-SD3pk0AvMd DP - DeepDyve ER -
