STRUCTURAL ANALYSIS

X-ray structure of hypothetical selenium-binding protein from Sulfolobus tokodaii, ST0059 ( http://www.proteopedia.org/wiki/index.php/2ece ) and the JenaLib Jmol viewer showing SBP 1 secondary structure [1]

Rat fatty acid binding protein 2IFB, a was found to have 92.5% homology to 14 KDa Selenium binding protein purified from rat liver using column chromatography and SDS-Gel techniques.([ref 3])

Explore SBP features and structural summary here [3].The domains of SBP are shown here [4] Notice how the domains are similar to the putative Isomerase domains of E.coli below.
