It is required for protein synthesis and is a central player in 1-carbon metabolism. In its activated form, S-adenosylmethionine (SAM), it is the methyl donor in hundreds of biologic transmethylation reactions and the donor of propylamine in polyamine synthesis. WebThe mTORC1 pathway regulates growth and metabolism in response to nutrient availability. In mammals, the mTORC1 pathway monitors the concentration of certain amino acids using dedicated nutrient sensors, which bind directly to their cognate metabolites. alberghi a loreto
