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
Methylation is catalysed by CheR, an S-adenosylmethionine-dependent methyltransferase, [1] which reversibly methylates specific glutamate residues within a coiled coil region, to form gamma-glutamyl methyl ester residues. [1] [2] The structure of the Salmonella typhimurium chemotaxis receptor methyltransferase CheR, bound to S ...
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).
One pathway utilizes a Δ 9-desaturase (DesA) that catalyzes a double bond formation in membrane lipids. Another pathway uses two proteins, DesC and DesB, together to act as a Δ 9-desaturase, which inserts a double bond into a saturated fatty acid-CoA molecule. This second pathway is regulated by repressor protein DesT.
The molecule folds into 2 domains, an N-terminal catalytic domain, which contains the catalytic and cofactor binding sites, and comprises a central 9-stranded beta-sheet, surrounded by 5 helices; and a C-terminal DNA recognition domain, which is formed by 4 small beta-sheets and 8 alpha-helices.
A well-characterized example of a methylation dependent protein–protein interaction is related to the selective methylation of lysine 9, by SUV39H1 on the N-terminal tail of the histone H3. [9] Di- and tri-methylation of this lysine residue facilitates the binding of heterochromatin protein 1 (HP1). Because HP1 and Suv39h1 interact, it is ...
