Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Use of a distant reporter group as evidence for a conformational change in a sensory receptor [PDF]

open access: yes, 1977
A highly sensitive method for demonstrating ligand-induced conformational changes in protein molecules in solution is described. The method utilizes an environmentally sensitive reporter group that is known to be distant from the active site.

Ligand-receptor binding kinetics in surface plasmon resonance cells: A Monte Carlo analysis

open access: yes, 2016
Surface plasmon resonance (SPR) chips are widely used to measure association and dissociation rates for the binding kinetics between two species of chemicals, e.g., cell receptors and ligands.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Factors affecting light energy transfer in some samarium complexes

open access: yesInternational Journal of Photoenergy, 2005
The photophysical properties of samarium ion in presence of 7-Acetoxy Coumarin 3-Carboxylic acid (ACC) or 1-(4-methoxyphenyl) 3-(4-t-butyl phenyl) 1,3-propandione (MBPK), which act as antenna of near-UV radiation, are studied in different homogeneous ...
