15N, 13C, and 1H resonance assignments of Jarastatin: a disintegrin of Bothrops jararaca

Biomol NMR Assign. 2022 Apr;16(1):37-40. doi: 10.1007/s12104-021-10056-1. Epub 2021 Nov 26.

Abstract

Disintegrins are a group of cysteine-rich proteins found in a wide variety of snake venoms. These proteins selectively bind to integrins, which play a fundamental role in the regulation of many physiological and pathological processes. Here, we report the NMR chemical shift assignments for 1H, 15N, and 13C nuclei in the backbone and side chains of recombinant disintegrin Jarastatin (rJast), which was further validated by secondary structure prediction using the TALOS-N server. Taken together, these data are essential to perform NMR-based experiments, including structure determination, backbone dynamics, mapping ligand sites and enabling a deeper understanding of the effect of hydrophobic surface clusters, which are important elements to stabilize some 3D proteins structure/folding.
