The H93G Myoglobin Cavity Mutant as a Versatile Template for Modeling Heme Proteins:Ferrous,Ferric,and Ferryl Mixed-Ligand Complexes with Imidazole in the Cavity
copper(II) azomethine imidate crystal structures
2016/5/23
One of the difficulties in preparing accurate ambient-temperature model complexes for heme proteins, particularly in the ferric state, has been the generation of mixed-ligand adducts: complexes with d...
Stark Effect Spectroscopy of Bacteriochlorophyll in Light-harvesting Complexes from Photosynthetic Bacteria
Stark effect Electric field effect Antenna complex Light harvesting complex Energy transfer BCP bacteriochlorophyll a protein RC reaction center
2016/5/23
The effects of an applied electric field on the Q y absorption and fluorescence spectra of three antenna complexes from photosynthetic bacteria have been measured at 77 K: the bacteriochlorophyll a pr...
Solution Properties of Synthetic Chlorophyllide-and Bacteriochlorophyllide-apomyoglobin Complexes
Solution Properties Chlorophyllide Bacteriochlorophyllide apomyoglobin Complexes
2016/5/20
Well-defined 1:1 complexes have been formed between apomyoglobin (apoMb) and a number of chlorophyllide derivatives. The chlorophyllides substitute for heme in the pocket of myoglobin. These include m...
Cofortification of ferric pyrophosphate and citric acid/trisodium citrate into extruded rice grains doubles iron bioavailability through in situ generation of soluble ferric pyrophosphate citrate complexes
iron bioavailability iron fortification extruded rice ferric pyrophosphate trisodium citrate iron deficiency
2018/11/29
Background: Iron fortification of rice is a promising strategy for improving iron nutrition. However, it is technically challenging because rice is consumed as intact grains, and ferric pyrophosphate ...
Regulation of Exocytosis by Syntaxin 4-Munc18c Complexes
Munc18c Syntaxin 4 SNARE diabetes
2015/5/25
Type 2 diabetes involves defects in glucose-stimulated insulin secretion (GSIS) from the pancreatic beta cells in combination with defects in peripheral (muscle and adipose) tissue glucose uptake. Bot...
The stability of T7 RNA polymerase elongation complexes and promoter function analysis by in vitro selection
Forward translocation model polymerase complex stability DNA structure
2014/12/11
The forward translocation model (paused or stalled polymerase moves forward in the absence of transcription, dissociation of the complex happens when hybrid is too short to stabilize the complex) is t...

Entropy-Enthalpy Compensation May Be a Useful Interpretation Tool for Complex Systems Like Protein-DNA Complexes: An Appeal to Experimentalists
Entropy-Enthalpy Compensation Useful Interpretation Tool Complex Systems Protein-DNA Complexes Experimentalists
2012/2/28
In various chemical systems enthalpy-entropy compensation (EEC) is a well-known rule of behavior, although the physical roots of it are still not completely understood. It has been frequently question...
Multipartite Quantum Entanglement Evolution in Photosynthetic Complexes
Multipartite Quantum Entanglement Evolution Photosynthetic Complexes
2012/2/28
We investigate the evolution of entanglement in the Fenna-Matthew-Olson (FMO) complex based on simulations using the scaled hierarchy equation of motion (HEOM) approach. We examine the role of multipa...
