Summary: A modified Wilbur-Anderson assay using a temperature controllable UV/Vis spectrophotometer and pH indicator phenol red is developed to improve the speed, accuracy, and precision of carbonic anhydrase (CA) activity determination. The results show that the modified assay is a simple and reliable method for routine measurement of CO2 hydration activity.

Summary: Carbonic anhydrases play important roles in various functions such as carbon assimilation, pH regulation, respiration, and photosynthesis. This study investigates the atomic level details of the enzyme's mode of action and reveals that the interaction between Glu106 and Thr199 is crucial for its activity. Additionally, the protein's secondary structure elements decrease with changes in pH conditions.

Summary: Stable and cost-effective carbonic anhydrase (CA)-like nanozymes, such as Fe10@CN-Mg, are efficient and sustainable for CO2 fixation. Fe10@CN-Mg, a novel iron-based nanomaterial, acts as a CA mimic with FeNx sites and Mg(OH)2 synergistically catalyzing CO2 conversion. It shows comparable kinetic constants, higher CaCO3 formation rate, and remains stable and active under extreme conditions and long storage times. Fe10@CN-Mg has been successfully applied for CO2 conversion into cyclic carbonates with high economic efficiency.

Summary: A mimetic CA (ZnHisGly) was designed and synthesized using zinc-based deep eutectic solvent (DES) to improve CO2 hydration and conversion efficiency. This mimetic CA showed advantages such as easy synthesis, high stability, and low cost, with superior catalytic performance compared to currently reported mimetic CA, especially showing significant performance improvement at higher pH and temperatures, suggesting promising prospects for industrial applications of DES-based CA mimics.

Summary: Carboxysomes are proteinaceous microcompartments responsible for a significant amount of CO2 fixation on Earth. They facilitate CO2 fixation by concentrating it in cells and converting HCO3- to CO2. The structural components and genetic context of atypical carboxysomes are described in this review.

Summary: Genetically engineered Corynebacterium glutamicum is introduced as a robust cell display platform for the in situ stabilization and low-cost production of carbonic anhydrase (CA). The cell-displayed CA shows high stability at high temperature and provides a promising technique for achieving highly efficient, sustainable, and low-cost CO2 capture for industrial applications.

Summary: A new assay based on pH value decline was established to quantify the activity of decarboxylase and capture released CO2. RuBisCo was hardly co-expressed with CadA in cascade enzymatic reaction. The strain with CadA and CA released the least amount of CO2 and had the best CO2 assimilation capability.

Summary: A series of hydrazonobenzenesulfonamides were designed, synthesized and evaluated for their inhibitory activity against human carbonic anhydrase (hCA) isoforms. The synthesized compounds showed inhibitory activity at low nanomolar levels against hCA I, II, IX and XII, with selectivity against hCA II isoform, as well as hCA IX and XII isoforms. Docking studies were conducted to understand the activity and selectivity of the most potent and selective hydrazones towards different CA isoforms.

Summary: This paper introduces a novel method to create a negative-emission enzymatic construction material (ECM) with self-healing capabilities, by catalyzing the condensation of CO2 and water to form calcium carbonate crystals. The resulting ECM has high strength and modulus, providing a new direction for developing environmentally friendly and low-cost construction materials.

Summary: The electrolysis of carbon capture solutions can convert them into carbon-based products without the need for energy-intensive CO2 recovery steps. Carbonic anhydrase enzymes can enhance CO2 capture by increasing the reaction rate between CO2 and alkaline solutions. A carbon microporous layer can suppress the deactivation of the catalyst caused by carbonic anhydrase.

Summary: A series of 4-methyl-1,2,3-benzoxathiazine-2,2-dioxides with different substituents were synthesized. The compounds showed nanomolar inhibitory effects on target hCA IX and XII, while exhibiting low or no inhibitory properties on off-target hCA I and moderate inhibition on hCA II. The derivatives of 4-methyl-1,2,3-benzoxathiazine 2,2-dioxide demonstrated excellent selectivity towards CA IX/XII over hCA I and very good selectivity towards CA IX/XII over hCA II.

Summary: A series of novel compounds were synthesized and evaluated for their inhibition of eukaryotic and human carbonic anhydrases. The results showed good inhibition against some target enzymes and weaker inhibition against others. These findings are important for the search for potential antifungal drugs.
