Carbon dioxide fixation by reversible pyrrole-2-carboxylate decarboxylase from Bacillus megaterium PYR2910.
Wieser M., Fujii N., Yoshida T., Nagasawa T.
Pyrrole-2-carboxylate decarboxylase from Bacillus megaterium PYR2910 attains a balanced reaction equilibrium with an equilibrium constant of 0.3-0.4 M. Therefore, the enzyme catalyzes the reverse carboxylation of pyrrole after addition of bicarbonate. For the synthesis of pyrrole-2-carboxylate, th ... >> More
Pyrrole-2-carboxylate decarboxylase from Bacillus megaterium PYR2910 attains a balanced reaction equilibrium with an equilibrium constant of 0.3-0.4 M. Therefore, the enzyme catalyzes the reverse carboxylation of pyrrole after addition of bicarbonate. For the synthesis of pyrrole-2-carboxylate, the reverse reaction was optimized and the equilibrium was shifted towards the carboxylate. The product yield was 230 mM (25.5 g/l) pyrrole-2-carboxylate from 300 mM pyrrole in a batch reaction and 325 mM (36.1 g/l) from 400 mM pyrrole in a fed-batch reaction, using both whole cells and the purified enzyme in a pH 8.0 reaction mixture with bicarbonate saturation of 1.9 M. Kinetic studies indicated, that bicarbonate is the reactive species used by this carbon dioxide-fixation enzyme. << Less

Inducible pyrrole-2-carboxylate decarboxylase, which catalyzes the decarboxylation of pyrrole-2-carboxylate to pyrrole and CO2 in stoichiometric amounts, was purified from Bacillus megaterium PYR2910.

Inducible pyrrole-2-carboxylate decarboxylase, which catalyzes the decarboxylation of pyrrole-2-carboxylate to pyrrole and CO2 in stoichiometric amounts, was purified from Bacillus megaterium PYR2910. The purity of the enzyme was shown by SDS/PAGE and gel-permeation HLPC. The enzyme has a molecular mass of approximately 98 kDa and consists of two identical subunits. It is highly specific for pyrrole-2-carboxylate, and also catalyzes the reverse reaction, the carboxylation of pyrrole. A unique feature of this enzyme is its requirement of an organic acid, such as acetate, propionate, butyrate or pimelate. A possible catalytic mechanism including a cofactor function of organic acid is discussed. << Less
