Methionine Biosynthesis (None)

Target: None
Molecular classification: Enzyme

Overview

Methionine biosynthesis refers to the cellular pathways that produce methionine, an essential sulfur-containing amino acid. While animals (including humans) cannot synthesize methionine and must obtain it from their diet, plants, fungi, and many microorganisms possess *de novo* biosynthetic pathways for methionine production. It's considered a good antimicrobial target because the enzymes involved are essential for microbial growth but absent in humans.

Mechanism of action

Inhibition of enzymes involved in the methionine biosynthesis pathway

Biological functions

Essential amino acid synthesisInitiator tRNA loadingPrecursor for S-adenosylmethionine (SAM)Cysteine biosynthesis (via transsulfuration)Polyamines biosynthesisPhospholipids (e.g., phosphatidylcholine) biosynthesisEthylene biosynthesis (in plants)
