The Gibbs free energy of binding (ΔG) is made up of enthalpic and entropic contributions and for reversible binding events can described as: (2.3)ΔG=ΔH−TΔS where ΔH defines enthalpy and ΔS, entropy at temperature T. The relationship between binding affinity (KD) and temperature (...
energy does not significantly change when screening 3ddopants. However, for 4dand 5ddopants, the situation is different. Because of the curvatures and the different position of adsorption minima for N2and NNH, the gap between the two curves closes when the binding energy of NNH is the strongest...
prediction performance, their accuracy have a great potential to be further improved. Since the protein-ligand binding affinity is determined by its absolute binding free energy [21], which is primarily specified by curvature [22], incorporating curvature information into the graph representation is ne...
The time-step employed in all simulation was 2 fs with a 12 Å non-bonded cutoff and with long-range non-bonded interactions evaluated every two steps. The systems were initially energy-minimized with a conjugate gradient method for three stages of 50,000 steps each: all atoms of the...

(Fig.7c, d). Furthermore, the detected enzyme-RBPs are highly enriched for specific enzymatic functions that rely on the use of nucleotide cofactors: ligases, which employ ATP or a similar energy donor, dehydrogenases that typically use NAD or NADP as proton acceptors, or CoA that we ...
(CID) was performed in the trap cell using an energy ramp from 12.3 eV to 17.8 eV at 300 m/zto 51 eV to 70.6 eV atm/z5000, followed by separation in the IMS cell. The postacquisition lock mass calibration was based on the doubly protonated signal of Glu-1fibrino...
Background Cyclic AMP receptor protein (CRP), also known as catabolite gene activator protein (CAP), is an important transcriptional regulator widely distributed in a variety of bacterial groups [1,2]. The biological processes under the regulation of CRP are highly diverse, including energy metaboli...
Computational techniques can speed up the identification of hits and accelerate the development of candidate molecules for drug discovery. Among techniques for predicting relative binding affinities, the most consistently accurate is free energy perturba
Identifying novel drug-target interactions is a critical and rate-limiting step in drug discovery. While deep learning models have been proposed to accelerate the identification process, here we show that state-of-the-art models fail to generalize to nov
