Effect of diminished activity of methionine adenosyl transferase on the bacteria’s DNA. Concept introduction: Methionine adenosyltransferase is an enzyme that catalyzes the synthesis of S-adenosylmethionine (SAM), by using methionine and ATP as the substrates. AdoMet acts as a methyl donor for the transmethylation reaction and propylamine donor in polyamine biosynthesis. Synthesis of SAM is the rate-limiting step in the methionine cycle.

Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
