2FE-2S FERREDOXIN FROM HALOARCULA MARISMORTUI
Overview
Haloarcula marismortui is an archaebacterium that flourishes in the, world's saltiest body of water, the Dead Sea. The cytosol of this organism, is a supersaturated salt solution in which proteins are soluble and, active. The crystal structure of a 2Fe-2S ferredoxin from H. marismortui, determined at 1.9 A is similar to those of plant-type 2Fe-2S ferredoxins, of known structure, with two important distinctions. The entire surface of, the protein is coated with acidic residues except for the vicinity of the, iron-sulphur cluster, and there is an insertion of two amphipathic helices, near the N-terminus. These form a separate hyperacidic domain whose, postulated function to provide extra surface carboxylates for solvation., These data and the fact that bound surface water molecules have on ...
