E., Drobny, G. D., & Waygood, E. B. (1986) Biochemistry 25, 7760-7769; Klevit, R. E., & Drobny, G. P. (1986) Biochemistry 25, 7770-7773; Klevit, R. E., & Waygood, E. B. (1986) Biochemistry 25, 7774-7781]. Two-dimensional homonuclear total coherence spectroscopy (TOCSY) allowed for more complete assignments of the side-chain spin systems than had been possible in the original studies. As well, two-dimensional 15N-1H heteronuclear spectroscopy was used to resolve a number of ambiguities present in the homonuclear spectra due to resonance redundancies. These analyses led to the correction of a number of resonance assignments that were made with the spectra that could be collected with the technology that existed 6 years ago. In addition, amide exchange rates and 3JNH coupling constants have been measured, extending the original analysis and yielding new structural information. All these data have been used to reexamine the folding topology of E. coli HPr. Structure calculations showed that the topology derived from the earlier NMR data, i.e., a four-stranded beta-sheet with three alpha-helices running along one side of the sheet, was essentially unchanged, although at the present level of analysis, a well-defined "helix B" could not be established with high confidence. In addition, the data reported here revealed the existence of two slowly-exchanging side-chain hydroxyl protons belonging to Ser31 and Thr59. Their behavior strongly suggests that these side chains are involved in hydrogen bonds.(ABSTRACT TRUNCATED AT 250 WORDS)"xsd:string |
