WebFinally, in line with a hypothesis that proline puckering allows controlled flexibility (Chow et al., Sci. Rep., 2024, 8, 13809), alterations in the puckering preferences are observed in the strained residues surrounding the mutational sites. 1 Introduction WebMay 11, 2024 · It has been suggested that this behavior emerges from puckering e ects induced by uorination of the proline ring. We use electronic struc- ture calculations to characterize the potential energy surface (PES) along puckering coordinates for a simple dipeptide model of proline and its uorinated derivatives.

WebDec 1, 2001 · Here we report the results of a statistical analysis of proline conformations using a large protein database. In particular, we found that proline residues with the preceding peptide bond in the cis state preferentially adopt a down puckering. Indeed, out of 178 cis proline residues, as many as 145 (81%) are down. By analyzing the 1–4 and 1 ... WebFeb 27, 2013 · In the current study, the puckering states of the Proline ring occurring in diproline segments (L Pro‐ L Pro) in proteins has been investigated with a segregation made on the basis of cis and trans states for the Pro‐Pro peptide bond and the conformational states for the diproline segment to investigate the effects of conformation of the diproline … the road to grace

WebMay 16, 2011 · Both, peptides and proteins containing 4-fluorinated proline derivatives can be stabilized by forcing the pyrrolidine ring in its favored puckering conformation. The fluorinated pyrrolidine rings of proline can preferably stabilize either a Cγ-exo or a Cγ-endo ring pucker in dependence of proline chirality (4R/4S) in a complex protein structure.
