Synthetic protein mimics structure, function of metalloprotein in nature
Date:12/10/2009

ing site consisting of three histidines and one glutamate.

In addition to their structural roles, the histidines and glutamate in the active site may also provide the two protons required for nitric oxide reduction.

"The designed protein models both the structure and the function of nitric-oxide reductase, and offers additional insight that the active site glutamate is required for both iron binding and reduction activity," Lu said. "The designed protein also serves as an excellent model for further mechanistic studies of nitric-oxide reductase."
