The 1.76 Å resolution crystal structure of glycogen phosphorylase b complexed with glucose, and CP320626, a potential antidiabetic drug
(2002)CP320626, a potential antidiabetic drug, inhibits glycogen phosphorylase in synergism with glucose. To elucidate the structural basis of synergistic inhibition, we determined the structure of muscle glycogen phosphorylase ...

Crystallographic and computational studies on 4-phenyl-N-(β-D- glucopyranosyl)-1H-1,2, 3-triazole-1-acetamide, an inhibitor of glycogen phosphorylase: Comparison with α-D-glucose, N-acetyl-β-D- glucopyranosylamine and N-benzoyl-N′-β-D-glucopyranosyl urea binding
(2008)4-Phenyl-N-(β-D-glucopyranosyl)-1H-1,2,3-triazole-1-acetamide (glucosyltriazolylacetamide) has been studied in kinetic and crystallographic experiments with glycogen phosphorylase b (GPb), in an effort to utilize its ...

Design of a modified mouse protein with ligand binding properties of its human analog by molecular dynamics simulations: The case of C3 inhibition by compstatin
(2011)The peptide compstatin and its derivatives inhibit the complement-component protein C3 in primate mammals and are potential therapeutic agents against the unregulated activation of complement in humans, but are inactive ...

Nitric-oxide reductase: Structure and properties of the catalytic site from resonance Raman scattering
(2002)We have applied resonance Raman spectroscopy to investigate the properties of the dinuclear center of oxidized, reduced, and NO-bound nitric-oxide reductase from Paracoccus denitrificans. The spectra of the oxidized enzyme ...

Proteus and the design of ligand binding sites
(2016)This chapter describes the organization and use of Proteus, a multitool computational suite for the optimization of protein and ligand conformations and sequences, and the calculation of pKα shifts and relative binding ...

Recognition of ribonuclease A by 3′-5′-pyrophosphate-linked dinucleotide inhibitors: A molecular dynamics/continuum electrostatics analysis
(2007)The proteins of the pancreatic ribonuclease A (RNase A) family catalyze the cleavage of the RNA polymer chain. The development of RNase inhibitors is of significant interest, as some of these compounds may have a therapeutic ...

Substitution of cysteine for glycine-α1-691 in the proα1(I) chain of type I procollagen in a proband with lethal osteogenesis imperfecta destabilizes the triple helix at a site C-terminal to the substitution
(1991)Skin fibroblast from a proband with lethal osteogenesis imperfecta synthesized a type I procollagen containing a cysteine residue in the α1(I) helical domain. Assay of thermal stability of the triple helix by proteinase ...

Substitutions for glycine α1-637 and glycine α2-694 of type I procollagen in lethal osteogenesis imperfecta: The conformational strain on the triple helix introduced by a glycine substitution can be transmitted along the helix
(1991)Two substitutions for glycine in the triple-helical domain were found in type I procollagen synthesized by skin fibroblasts from two probands with lethal osteogenesis imperfecta. One was a substitution of valine for glycine ...

Superhelices of poly[2-(acetoacetoxy)ethyl methacrylate]
(2004)Poly[2-(acetoacetoxy) ethyl methacrylate] (PAEMA) homopolymers were found to self-assemble into hierarchical superstructures, that is, double-stranded helical tubes of either screw sense (scanning force microscopy). Both ...

Two ligand-binding sites in the O2-sensing signal transducer HemAT: Implications for ligand recognition/discrimination and signaling
(2006)We have identified a ligand (CO) accommodation cavity in the signal transducer sensor protein HemAT (heme-based aerotactic transducer) that allows us to gain single-molecule insights into the mechanism of gas sensor proteins. ...
