Ubiquitin is a small (8.6 kDa) regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ubiquitously. It was discovered in 1975 [1] by Gideon Goldstein and further characterized throughout the late 1970s and 1980s. [2] Four genes in the human genome code for ubiquitin: UBB, UBC, UBA52 and RPS27A. [3]
In biochemistry, an esterase is a class of enzyme that splits esters into an acid and an alcohol in a chemical reaction with water called hydrolysis (and as such, it is a type of hydrolase).

Eventually, [these] thioesters could have served to usher in ATP through its ability to support the formation of bonds between phosphate groups. However, due to the high free energy change of thioester's hydrolysis and correspondingly their low equilibrium constants, it is unlikely that these compounds could have accumulated abiotically to any ...
This linkage is an ester bond that chemically binds the carboxyl group of an amino acid to the terminal 3'-OH group of its cognate tRNA. [7] It has been discovered that the amino acid moiety of a given aa-tRNA provides for its structural integrity; the tRNA moiety dictates, for the most part, how and when the amino acid will be incorporated ...
Protein primary structure is the linear sequence of amino acids in a peptide or protein. [1] By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end. Protein biosynthesis is most commonly performed by ribosomes in cells. Peptides can also be synthesized in the ...
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 .

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.
