We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

'''TN5 TRANSPOSASE: 20MER OUTSIDE END 2 MN COMPLEX'''
+

-
==Overview==
+
-
A synaptic complex of Tn5 transposase with an extended outside end DNA duplex was prepared and crystallized, and its crystal structure was determined in an effort to reveal the role of metal ions in catalysis. Two Mn2+ ions bound to the active site when a single nucleotide of donor DNA was added to the 3' end of the transferred strand. Marked conformational changes were observed in the DNA bases closest to the active site. The position of the metal ions and the conformational changes of the DNA provide insight into the mechanism of hairpin formation and cleavage, and is consistent with a two-metal model for catalysis.
