Twenty crystal structures of bromodomain and PHD finger containing protein 1 (BRPF1)/ligand complexes reveal conserved binding motifs and rare interactions


Zhu, Jian; Caflisch, Amedeo (2016). Twenty crystal structures of bromodomain and PHD finger containing protein 1 (BRPF1)/ligand complexes reveal conserved binding motifs and rare interactions. Journal of Medicinal Chemistry, 59(11):5555-5561.

Abstract

BRPF1 plays a scaffolding role in transcription. We report on fragment screening by high-throughput docking to the BRPF1 bromodomain which resulted in six chemotypes with very favorable ligand efficiency (0.45-0.50 kcal/mol per non-hydrogen atom). Twenty crystal structures of BRPF1/ligand complexes show structural conservation in the acetyllysine binding site, common binding motifs, and unusual interactions (e.g., the replacement of a conserved water molecule). The structural information is useful for the design of chemical probes.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
