Study of voltammetry behavior of complexation for nano-copper sulfate (NCSu) with cefdinir antibiotic (CFD) using glassy carbon electrode (GCE) in mixed 5% v/v (DMF-H2O) solvents [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research, 2018
Cyclic voltammetry of nano-copper (II) complex (NCSu) with Cefdinir antibiotic (CFD) was studied using a glassy carbon electrode (GCE) in 0.1M KCl as a supporting electrolyte in 5% (v/v) mixed (DMF-H2O) solvent at two temperatures (298.15, 303.15 K).

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Thermodynamic parameters of phenylglycine interaction with UO2 2+, La3+ and Zr4+

open access: yesBMC Chemistry, 2023
Phenylglycine interactions with (UO2 2+, La3+ and Zr4+) transition metal ions were studied at different ionic strengths and different temperature degrees applying Bjerrum’s method. The work determine and discuss both the thermodynamic stabilities and the

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Paper ionophoretic technique in the study of biologically important beryllium(II) / cobalt(II)-homoserine binary complexes in solution

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2010
Quantitative indication of the process of forming a complex comes from the evaluation of the stability constants, which characterize the equilibria corresponding to the successive addition of ligands.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be
