A general Monte Carlo/simulated annealing algorithm for resonance assignment in NMR of uniformly labeled biopolymers
Abstract We describe a general computational approach to site-specific resonance assignments in multidimensional NMR studies of uniformly 15N,13C-labeled biopolymers, based on a simple Monte Carlo/simulated annealing (MCSA) algorithm contained in the program MCASSIGN2. Input to MCASSIGN2 includes lists of multidimensional signals in the NMR spectra with their possible residue-type assignments (which need not be unique), the biopolymer sequence, and a table that describes...

Improved accuracy in measuring one-bond and two-bond 15N,13Cα coupling constants in proteins by double-inphase/antiphase (DIPAP) spectroscopy
Abstract An extension to HN(CO-α/β-N,Cα-J)-TROSY (Permi and Annila in J Biomol NMR 16:221â??227, 2000) is proposed that permits the simultaneous determination of the four coupling constants 1 J Nâ?²(i)Cα(i), 2 J HN(i)Cα(i), 2 J Cα(iâ??1)Nâ?²(i), and 3 J Cα(iâ??1)HN(i) in 15N,13C-labeled proteins. Contrasting the original scheme, in which two separate subspectra exhibit the 2 J CαNâ?² coupling as inphase and antiphase splitting (IPAP), we...

Prediction of Xaa-Pro peptide bond conformation from sequence and chemical shifts
Abstract We present a program, named Promega, to predict the Xaa-Pro peptide bond conformation on the basis of backbone chemical shifts and the amino acid sequence. Using a chemical shift database of proteins of known structure together with the PDB-extracted amino acid preference of cis Xaa-Pro peptide bonds, a cis/trans probability score is calculated from the backbone and 13Cβ chemical shifts of the proline and its neighboring residues. For an arbitrary number of input chemical shifts, which may include Pro-13Cγ, Promega calculates the statistical probability that a Xaa-Pro peptide bond...
