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]
Query name: SBP 1 ( 2ECE )
Structure prediction by SABLE
Data source: Derived from the SABLE server prediction
WARNING! Given sequence appeared to be a soluble protein, no TM domains found!
Output format is the following:
1st line -> residue numeration
2nd line -> query amino acid sequence
3rd line -> trans-membrane domain prediction (T-TM region, N-soluble part)

STRUCTURAL COMPARISONS
Surface Structure of SBP: Note the few clefts compared to the DNA isomerase shown below.
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])
