'''CRYSTAL STRUCTURE OF CU(I)CUSF'''
===CRYSTAL STRUCTURE OF CU(I)CUSF===




==Overview==
<!--
Methionine-rich motifs have an important role in copper trafficking factors, including the CusF protein. Here we show that CusF uses a new metal recognition site wherein Cu(I) is tetragonally displaced from a Met2His ligand plane toward a conserved tryptophan. Spectroscopic studies demonstrate that both thioether ligation and strong cation-pi interactions with tryptophan stabilize metal binding. This novel active site chemistry affords mechanisms for control of adventitious metal redox and substitution chemistry.
The line below this paragraph, {{ABSTRACT_PUBMED_18157124}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 18157124 is the PubMed ID number.
