We shall use the SARS-CoV-2 main protease as an example. Starting from a structure downloaded from the Protein Data Bank, we discuss how to prepare the coordinates file, taking into account the known biochemical background information of the target protein. The reader will find that this preparation step takes up most of the effort before the target is ready for screening. The steps for uploading the target structure and defining the search volume by critical residues, and the main parameters to use, are outlined. When this protocol is followed, the user will expect to obtain a ranked list of small approved drug compounds docked into the target structure. The results can be readily examined graphically on the web site or downloaded for studying in a local molecular graphics program such as PyMOL.</span></p> Yu Wai Chen Chin-Pang Bennu Yiu Kwok-Yin Wong Copyright (c) 2021 Yu Wai Chen, Chin-Pang Bennu Yiu, Kwok-Yin Wong https://creativecommons.org/licenses/by-nc-sa/4.0 2021-05-26 2021-05-26 8 COVID 19 Special Issue e148 e148 10.14440/jbm.2021.351
