Homology model of the predicted hydrolase Bfl316. (template:1OZ9.pdb; hypothetical protein Aq_1354 of Aquifex aeolicus). The model starts at residue 33, a phenylalanine. The family signature (UPF, residues from 113 to 130 in Bfl316) is indicated in ball-and-stick. Note that in the template 1OZ9 from pdb databank the structure coordinates are exactly known, however the protein function explained in results was not previously apparent.
