Methylesterase (ME) removes a methyl group from the Υ-glutamyl methyl esther residues of methyl-accepting chemotaxis proteins. ME participates in several metabolic pathways. Protein phosphatase ME is involved in the reversible methylation of protein phosphatase 2A which is active in cellular regulation.
- CheB ME is a phosphorylation-activated response regulator involved in reversible modification of bacterial chemotaxis receptors[1]. See Chemotaxis protein.
- Pectin ME causes demethylation of cell wall polygalactorunanas. It is involved in pectin digestion. The reaction products liberate frothing agents causing bloating in cattle[2].
- Aclacinomycin ME modifies the aklavinone skeleton in the biosynthesis of anthracyclins in Streptomyces species[3].
- Protein phosphatase ME is a key regulator of protein phosphatase 2A[4].
- 4-o-methyl-glucuronoyl ME has a significant role in biomass degradation[5].
