(1)H, (13)C, (15)N backbone and side chain NMR resonance assignments for E73 from Sulfolobus spindle-shaped virus ragged hills, a hyperthermophilic crenarchaeal virus from Yellowstone National Park.

Abstract

Crenarchaeal viruses are commonly found in hyperthermal acidic environments such as those of Yellowstone National Park. These remarkable viruses not only exhibit unusual morphologies, but also display extreme genetic diversity. However, little is known about crenarchaeal viral life cycles, virus-host interactions, and their adaptation to hyperthermophilic environments. In an effort to better understand the functions of crenarchaeal viruses and the proteins encoded by their genomes, we have undertaken detailed structural and functional studies of gene products encoded in the open reading frames of Sulfolobus spindle-shaped virus ragged hills. Herein, we report ((15)N, (13)C, (1)H) resonance assignments of backbone and side chain atoms of a 19.1 kDa homodimeric E73 protein of SSVRH.
