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 most commonly used alcohol is methanol, producing fatty acid methyl esters (FAME). When ethanol is used fatty acid ethyl esters (FAEE) are created. Other alcohols used for the production of biodiesel include butanol and isopropanol. Fatty acid ethyl esters are biomarkers for the consumption of ethanol (alcoholic beverages). [1] [2] [3]
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.
Protein methylation is a type of post-translational modification featuring the addition of methyl groups to proteins.It can occur on the nitrogen-containing side-chains of arginine and lysine, [1] [2] but also at the amino- and carboxy-termini of a number of different proteins.
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 ...
In enzymology, a fatty-acid O-methyltransferase (EC 2.1.1.15) is an enzyme that catalyzes the chemical reaction. S-adenosyl-L-methionine + a fatty acid S-adenosyl-L-homocysteine + a fatty acid methyl ester
Fatty acid methyl esters (FAME) are a type of fatty acid ester that are derived by transesterification of fats with methanol. The molecules in biodiesel are primarily FAME, usually obtained from vegetable oils by transesterification. They are used to produce detergents and biodiesel. [1]
