Figure 1: Model of a proposed CA-mediated CO2 absorber to be used in industrial CDR processes. Highlighted are specific biochemical and biophysical characteristics that would be ideal for a bio-catalytic CA (green) immobilized on a resin (shown as mesh) within a CO2 absorber. These would include: a compact and oligomeric structure to have thermal stability, exhibit enzyme activity in a broad pH range, and resistance to anionic inhibition (shown are common anions found in fossil-fuel combustion by-products). Figure was made in part using PyMol [22]. CA structure shown is that of the α-CA from Thiomicrospira crunogena (PDB: 4XZ5) [15].
