Abstract excerpt
Carbonic anhydrase (CA) is a ubiquitous enzyme catalyzing the equilibration of carbon dioxide, protons, and bicarbonate. For several acid/base-coupled membrane carriers it has been shown that the catalytic activity of CA supports transport activity, an interaction coined "transport metabolon." We have reported that CA isoform II (CAII) enhances lactate transport activity of the monocarboxylate transporter isoform...
