The structure of a reduced mutant T4 glutaredoxin

[摘要]

The mutant T4 glutaredoxin where the active site residues Val¹⁵ and Tyr¹⁶ have been substituted by Gly and Pro, respectively, crystallizes in a form where the active site disulfide is accessible to reagents. Treatment of the crystals with dithiotreitol causes very subtle changes in the overall glutaredoxin structure. The main differences are seen around the active site where the sulfurs of Cys¹⁴ and Cys¹⁷ move apart slightly.
