Bacterial and fungal cytoplasmic proteins and enzymes

Bacterial and fungal cytoplasmic proteins and enzymes encompass a vast array of intracellular molecules that serve as the primary targets for many antimicrobial agents. In bacteria, key targets include the 30S and 50S ribosomal subunits, which are inhibited by classes such as aminoglycosides and macrolides to disrupt protein synthesis (StatPearls, "Antibiotics", 2023). Enzymes like DNA gyrase and topoisomerase IV are targeted by fluoroquinolones to prevent DNA replication, while the folate synthesis pathway is inhibited by sulfonamides (NCBI, "Mechanisms of Bacterial Resistance", 2021). In fungi, cytoplasmic enzymes involved in the synthesis of essential components like ergosterol (e.g., lanosterol 14-alpha-demethylase) are targeted by azole antifungals to compromise cell membrane integrity (PubMed, "Antifungal Agents", 2022). These targets are critical for pathogen viability, and their structural differences from human homologs allow for selective toxicity. However, the broad nature of this category reflects the complexity of antimicrobial therapy and the ongoing challenge of drug resistance.
