Solution NMR and X-ray crystal structures of membrane-associated Lipoprotein-17 domain reveal a novel fold.

ABSTRACT: The conserved Lipoprotein-17 domain of membrane-associated protein Q9PRA0_UREPA from Ureaplasma parvum was selected for structure determination by the Northeast Structural Genomics Consortium, as part of the Protein Structure Initiative's program on structure-function analysis of protein domains from large domain sequence families lacking structural representatives. The 100-residue Lipoprotein-17 domain is a "domain of unknown function" (DUF) that is a member of Pfam protein family PF04200, a large domain family for which no members have characterized biochemical functions. The three-dimensional structure of the Lipoprotein-17 domain of protein Q9PRA0_UREPA was determined by both solution NMR and by X-ray crystallography at 2.5 Å. The two structures are in good agreement with each other. T
