Introduction: The hydration/dehydration of CO2 catalyzed by carbonic anhydrases (CAs, EC 4.2.1.1) is a crucial physiological reaction for the survival of all living organisms because it is connected with numerous biosynthetic and biochemical pathways requiring CO2 or HCO3-, such as respiration, photosynthesis, carboxylation reactions, pH homeostasis, secretion of electrolytes, transport of CO2, bicarbonate, etc. Areas covered: The bacterial genome encodes CAs belonging to the ?-, ?-, and ?-CA classes able to ensure the survival and/or satisfying the metabolic needs of the bacteria, as demonstrated by in vivo and in vitro experiments. The discovery of new anti-infectives that target new bacterial pathways, such as those involving CAs, may lead to effective therapies against diseases subject to the antibiotic resistance. This aspect is important in pharmaceutical and biomedical research but received little attention till recently. Expert opinion: An overview of the potential use of CAs in biomedical applications, as drug targets, bioindicators, and within artificial organs is presented. The discovery of thermostable bacterial CAs allowed the use of CAs in biotechnological applications, but patents related to the use of bacterial CAs in the development of pharmacological agents are scarce.
