This study explores the effects of amino acid analogs, specifically fluoroleucine, on wild-type Salmonella and their growth on minimal media. Isopropylmalate synthase, the first committed enzyme in leucine biosynthesis, is analyzed to understand why normal amino acids are not synthesized and what occurs when analogs are incorporated into proteins. The nature of mutant variants that can grow in the presence of fluoroleucine is examined, providing insights into bacterial adaptability and metabolic pathways.
