Once in position, the water molecule acts as a nucleophile, and attacks the carbonyl group of the ester bond between the nascent protein and the tRNA. The hydrolysis of the ester bond causes the release of the nascent protein and the disassembly of the ribosome and termination complex. [37] Hydrolysis of ester bond to release nascent protein [37]
Cholesteryl oleate, a member of the cholesteryl ester family. Cholesteryl esters are a type of dietary lipid and are ester derivatives of cholesterol. The ester bond is formed between the carboxylate group of a fatty acid and the hydroxyl group of cholesterol. Cholesteryl esters have a lower solubility in water due to their increased ...
Furthermore, the TetM protein is found to allow aminoacyl-tRNA molecules to bind to the ribosomal acceptor site, despite being concentrated with tetracyclines that would typically inhibit such actions. The TetM protein is regarded as a ribosomal protection protein, exhibiting GTPase activity that is dependent upon ribosomes.
Homologous to the ATP-binding and catalytic sites of E1 activator proteins, ATG7 uses its cysteine residue to create a thiol-ester bond with free Ubiquitin molecules. [ 9 ] [ 12 ] Through UPS, Ubiquitin will continue to bind to other autophagy-related proteins, E2 conjugation proteins and E3 protein ligases, to attach Ubiquitins to a target ...
Phosphatidylserine (PS) is the major acidic phospholipid class that accounts for 13–15% of the phospholipids in the human cerebral cortex. [7] In the plasma membrane, PS is localized exclusively in the cytoplasmic leaflet where it forms part of protein docking sites necessary for the activation of several key signaling pathways.
The result of this sequential cascade is to bind ubiquitin to lysine residues on the protein substrate via an isopeptide bond, cysteine residues through a thioester bond; serine, threonine, and tyrosine residues through an ester bond; or the amino group of the protein's N-terminus via a peptide bond.

Esterases cleave ester bonds in lipids and phosphatases cleave phosphate groups off molecules. An example of crucial esterase is acetylcholine esterase , which assists in transforming the neuron impulse into the acetate group after the hydrolase breaks the acetylcholine into choline and acetic acid .
