TP47, THE 47-KILODALTON LIPOPROTEIN OF TREPONEMA PALLIDUM
Overview
Syphilis is a complex sexually transmitted disease caused by the, spirochetal bacterium Treponema pallidum. T. pallidum has remained, exquisitely sensitive to penicillin, but the mode of action and lethal, targets for beta-lactams are still unknown. We previously identified the, T. pallidum 47-kDa lipoprotein (Tp47) as a penicillin-binding protein, (PBP). Tp47 contains three hypothetical consensus motifs (SVTK, TEN, and, KTG) that typically form the active center of other PBPs. Yet, in this, study, mutations of key amino acids within these motifs failed to abolish, the penicillin binding activity of Tp47. The crystal structure of Tp47 at, a resolution of 1.95 A revealed a fold different from any other known PBP;, Tp47 is predominantly beta-sheet, in contrast to the alpha/beta-fold, common ...
