Amino acids play important roles in the metabolism and biology of bacteria. Like all living organisms,
bacteria require amino acids as building blocks for proteins. Bacteria can obtain amino acids from their
environment or synthesize them de novo using specific metabolic pathways. Many types of bacteria are
able to break down proteins into their constituent amino acids using proteases and peptidases. These
amino acids can then be used for the synthesis of new proteins or as a source of carbon and nitrogen for
energy production.
