The enzyme activity of glycoside hydrolysis was determined using the p-nitrophenyl (pNP) and 3,5-dinitrosalicylic acid (DNS) methods as previously described113,114. For the pNP method,pNP-β-D-xylopyranoside (pNP-βXyl) (Haohong Biomedical Technology, Shanghai, China),pNP -β-D-mannopyranosi...
UvrD, a model for non-hexameric Superfamily 1 helicases, utilizes ATP hydrolysis to translocate stepwise along single-stranded DNA and unwind the duplex. Previous estimates of its step size have been indirect, and a consensus on its stepping mechanism is lacking. To dissect the mechanism underlying...

1). The catalytic dyad residues are key for hydrolysis in which HIS41 functions as a general base [6], [64]. SARS-CoV-2 Mpro domains I (residue 10–99) and II (100–183) consist of an antiparallel β-barrel structure [2] that form the catalytic domains of the protein as the ...
Finally, the solvent-excluded coordination spheres of Hans-LanM should outperform Mex-LanM in RE/actinide separation23, luminescence-based sensing21,26 and stabilization of hydrolysis-prone ions. Continued characterization of the coordination and supramolecular principles of biological f-element recognition ...
The energy for this process is obtained from the hydrolysis of the dNTP into dNMP + pyrophosphate (PPi). Then, we propose the following DNA-centered translocation mechanism in DNA replication: Soon after the new nucleotide is branched to the replicated strand, the newly formed base-pair ...
Using a titration of ATPγS, we were able to gradually shorten OAD arrays in vitro owing to the low hydrolysis rate (Fig. 6c). Increasing the ATPγS does not cut the array into many shorter segments randomly, but rather sequentially shortens the arrays, suggesting ATP hydrolysis is more ...
