The enzyme Pimelyl-[acyl-carrier protein] methyl ester esterase (EC 3.1.1.85, BioH; systematic name pimelyl-[acyl-carrier protein] methyl ester hydrolase ...
The enzyme protein-glutamate methylesterase (EC 3.1.1.61) catalyzes the reaction . protein L-glutamate O 5-methyl ester + H 2 O protein L-glutamate + methanol. This enzyme is a demethylase, and more specifically it belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds.
The enzyme protein phosphatase methylesterase-1 (EC 3.1.1.89, PME-1, PPME1; systematic name (phosphatase 2A protein)-leucine ester acylhydrolase [1] [2] catalyses the reaction [phosphatase 2A protein]-leucine methyl ester + H 2 O ⇌ {\displaystyle \rightleftharpoons } [phosphatase 2A protein]-leucine + methanol
This article needs attention from an expert in biochemistry.The specific problem is: someone with a solid grasp of the full scope of this subject and of its secondary and advanced teaching literatures needs to address A, the clear structural issues of the article (e.g., general absence of catabolic biosynthetic pathways, insertion of macromolecule anabolic paths before all building blocks ...
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
The structure explains many of the interactions observed between JHE and its substrates and inhibitors, such as the preference for methyl esters vs. ethyl or isopropyl esters, and long hydrophobic backbones. [26] The enzyme is extremely efficient, with a cat/Km of at least 3 x 107 M-1 s-1.
The general mechanism for methyl transfer is a S N 2-like nucleophilic attack where the methionine sulfur serves as the leaving group and the methyl group attached to it acts as the electrophile that transfers the methyl group to the enzyme substrate.
m5C - those that generate C5-methylcytosine EC 2.1.1.37 m6A and m4C methyltransferases are found primarily in prokaryotes (although recent evidence has suggested that m6A is abundant in eukaryotes [ 1 ] ). m5C methyltransferases are found in some lower eukaryotes, in most higher plants, and in animals beginning with the echinoderms .
