Kinetic And Anion Inhibition Studies Of A Beta-Carbonic Anhydrase (fbica 1) From The C-4 Plant Flaveria Bidentis
Several beta-carbonic anhydrases (CAs, EC 4. 2. 1. 1) are present in all land plants examined thus far. Here we report the first detailed biochemical characterization of one such isoform, FbiCA 1, from the C-4 plant Flaveria bidentis, which was cloned, purified and characterized as recombinant protein. FbiCA 1 has an interesting CO2 hydrase catalytic activity (k (cat) of 1. 2 x 10 (5) and k (cat) /K-m of 7. 5 x 10 (6) M-1 x s (-1)) and was moderately inhibited by most simple/complex inorganic anions. Potent FbiCA 1 inhibitors were also detected, such as trithiocarbonate, diethyldithiocarbamate, sulfamide, sulfamic acid, phenylboronic acid and phenylarsonic acid (K (I) s in the range of 4-60 mu M). Such inhibitors may be used as tools to better understand the role of various beta-CA isoforms in photosynthesis. (C) 2013 Elsevier Ltd. All rights reserved
