    Protein Summary

    Gene AF1534 (PF02036, cl01225) from Archaeoglobus fulgidus translates into the protein NP_070363.1 from the SCP2 sterol transfer family (PF02036).  

    Pre-SCOP classifies 3bn8 in the alpha+beta class, sterol carrier protein-like (super)family. A structural similarity search using DALI returns as top hits the estradiol beta-dehydrogenase protein 1ikt (Z=11) and the SCP-2 proteins 1c44, 2qzt and 3bdq (Z=10). In the 3bn8 crystal structure there are 2 monomers in each asymmetric unit. The SEC data and surface interaction calculation results suggest that the likely biomolecule is a dimer. Compared with 1IKT, 3bn8  shares the same fold with a hydrophobic tunnel in the structure. There is an OXN or sterol like electron density in this tunnel which is modeled as an unknown ligand near residue Tyr-45.
