Dock Denovo Run
The Denovo module of DOCK is a relatively new feature (as of Fall 2016) that constructs new ligand molecules inside a protein active site from a library of user-specified "fragments". These fragments are common chemical functional groups, or building blocks, that are typically selected from a ZINC library of millions of compounds based off of their frequency of appearance. These fragments are classified as scaffolds, linkers, or side chains, according to the number of atomic positions that are permitted to seed growth: 3, 2, and 1 atoms, respectively. Thus, a scaffold could seed growth on three different atoms, having three linkers bonded to each position, and a linker could seed growth on two positions, and a side-chain on one position.
Once the molecules are built within the active site, their interactions with the protein are scored using the user-specified method of scoring. This tutorial will walk through the steps needed to run a Denovo calculation on the Beta Trypsin system from the 2016 DOCK tutorial. This method will utilize the multi-grid scoring function, called through the descriptor score.
Preparing The Files
Before the Denovo module can be run, please ensure you have ran the DOCK 2016 tutorial and have all the resulting files. The tutorial can be accessed through here.
