Attention is focused on l-5,5-dimethylproline (dmP) as a substitute to lock l-proline (Pro) in a cis conformation in peptides and proteins, to prevent cis/trans isomerization when a protein with cis X-Pro peptide groups unfolds. Procedures have been

New general approach for determining the solution structure of a ligand bound weakly to a receptor: structure of a fibrinogen A?-like peptide bound to thrombin(S195A) obtained using NOE distance constraints and an ECEPP/3 flexible docking program

Autor: Elsie E. DiBella, Harold A. Scheraga, Muriel C. Maurer, Jean-Yves Trosset, Cathy C. Lester

Publikováno v: Proteins: Structure, Function, and Genetics. 34:29-48

A new approach incorporating flexible docking simulations and NMR data is presented for calculating the bound conformation of a ligand that interacts weakly with an enzyme. This approach consists of sampling directly the conformation of a flexible li

A Caffeoylcyclohexane-1-Carboxylic Acid Derivative From Asimina Triloba

Autor: Paul Feeny, Cathy C. Lester, Meena Haribal

Publikováno v: Phytochemistry. 49:103-108

Three caffeoyl derivatives of 1,3,4,5-tetrahydroxycyclohexane 1-carboxylic acid, one of them an oviposition stimulant for the zebra swallowtail butterfly, Eurytides marcellus , were isolated from Asimina triloba . The structure of the active isomer,

Structural Characterization of an Analog of the Major Rate-Determining Disulfide Folding Intermediate of Bovine Pancreatic Ribonuclease A

Autor: Cathy C. Lester, Diane E. Zimmerman, Sakurako Shimotakahara, Harold A. Scheraga, Gaetano T. Montelione, John H. Laity

Publikováno v: Biochemistry. 36:12683-12699

The major rate-determining step in the oxidative regeneration of bovine pancreatic ribonuclease A (RNase A) proceeds through des-[40-95] RNase A, a three-disulfide intermediate lacking the Cys40-Cys95 disulfide bond. An analog of this intermediate, [

Structure-function studies of mEGF: Probing the type Iβ-turn between residues 25 and 26

Autor: Cathy C. Lester, Baiyang Wang, Ray Wu, Harold A. Scheraga

Publikováno v: Journal of Protein Chemistry. 14:753-762

The interaction between epidermal growth factor (EGF) and its receptor molecule is not completely understood and has received much attention recently. Studies combining site-directed mutagenesis and NMR spectroscopy have identified a number of EGF re
