Template:STRUCTURE 3uw0 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. Pectin ME causes demethylation of cell wall polygalactorunanas. It is involved in pectin digestion. The reaction products liberate frothing agents causing bloating in cattle. Aclacinomycin ME modifies the aklavinone skeleton in the biosynthesis of anthracyclins in Streptomyces species.
