Biomolecule Toolkit

ChemAxon's novel Biomolecule Toolkit is bringing the HELM standard to life. The ChEMBL v21DB contains ~ 20000 peptides published in both MOL and HELM format, which we used as a benchmark for measuring the ability of our tool to start from a set of chemical representations, convert it to HELM, and index it in a database. Finally we performed queries on the indexed content, which were not possible previously using the default ChEMBL web interface. Along the way we encountered a few challenges and data issues, of which a select few are detailed below. Our tool provides a solution for these and may help to improve ChEMBL and other datasets.
