High affinity divalent cation binding to actin. Effect of low affinity salt binding.
Monomeric actin labeled with the fluorescent probe N-iodoacetyl-N'-(5-sulfo-1-naphthyl)ethylenediamine (1,5-I-AEDANS-actin) displays a fast fluorescence intensity increase immediately upon addition of salt and then a slow fluorescence intensity change concurrent with Ca2+/Mg2+ exchange at the high affinity divalent cation binding site on actin.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

A cDNA clone encoding the high affinity Ca2+-binding protein (HACBP) of rabbit skeletal muscle sarcoplasmic reticulum was isolated and sequenced. The cDNA encoded a protein of 418 amino acids, but a comparison of the deduced amino acid sequence with the ...

Summary: The affinity of transcription factors (TFs) for their target DNA is a critical determinant of gene expression. Whether the DNA-binding domain (DBD) of TFs alone can regulate binding affinity to DNA is an important question for identifying the ...

Mass spectrometry based identification of AMP‐O‐Tris generated by Thermococcus onnurineus Cas10
Isolated Thermococcus onnurineus Cas10 generates the noncanonical ATP‐derived product AMP‐O‐Tris while in Tris‐containing buffer as identified via mass spectrometry, revealing relaxed nucleophile selectivity under isolated conditions. These findings suggest that multiprotein Csm complex assembly restricts Cas10 reactivity toward canonical cyclic ...

Estimating binding affinity between a target protein and the ligand is a crucial step in the drug discovery process. In computer aided drug design (CADD), the problem can be divided into two steps, finding the correct binding pose and estimating binding ...

Mechanical affinity as a new metrics to evaluate binding events
Binding affinity is measured by dissociation constant, Kd, which uses concentration as units. The universal concentration units facilitate direct comparison of affinities for different binding events. However, Kd is a thermodynamic parameter, which lacks

Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

The cloning , expression and characterisation of bacterial chitin-binding proteins from pseudomonas aeruginosa , serratia marcescens, photorhabdus luminescens and photorhabdus asymbiotica. [PDF]
It is well recognised that most proteins are subject to post translational modifications and that these modifications can have specific effects on the biological properties and functions of these proteins.
