Carbonic anhydrase in relation to higher plants

摘要: The review incorporates recent information on carbonic anhydrase (CA, EC: 4.2.1.1) pertaining to types, homology, regulation, purification, in vitro stability, and biological functions with special reference higher plants. CA, a ubiquitous enzyme prokaryotes organisms represented by four distinct families, is involved diverse processes, including pH CO2 transfer, ion exchange, respiration, photosynthetic fixation. CA from plants traces its origin exhibits compartmentalization among their organs, tissues, cellular organelles commensurate specific functions. In leaves, represents 1−20 % of total soluble protein abundance next only ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCO) chloroplast, facilitating supply phosphoenol pyruvate carboxylase C4 CAM RuBPCO C3 It confers significance as an efficient biochemical marker for carbon sequestration environmental amelioration the current global warming scenario linked elevated concentrations.
