Expressed protein ligation: a new tool for the biosynthesis of cyclic polypeptides.

abstract：:Nudix hydrolases catalyze the hydrolysis of nucleoside diphosphates linked to other moieties X, and contain the sequence motif or Nudix box, GX5EX7REUXEEXGU. The mechanisms of Nudix hydrolases are highly diverse in the position on the substrate. In this paper, we examined the sequences and structures of the MutT/Nudix...
