Prokaryotic Argonautes Function beyond Immunity by Unlinking Replicating Chromosomes.

abstract：:We have determined the 2.0 A crystal structure of a fragment of human fibronectin encompassing the seventh through the RGD-containing tenth type III repeats (FN7-10). The structure reveals an extended rod-like molecule with a long axis of approximately 140 A and highly variable relationships between adjacent domains. ...
