G. Protoschillkrebs et al., CONSUMPTION OF CARBONYL SULFIDE (COS) BY HIGHER-PLANT CARBONIC-ANHYDRASE (CA), Atmospheric environment, 30(18), 1996, pp. 3151-3156
Carbonic anhydrase (CA), isolated from pea leaves, was found to consum
e carbonyl sulphide (COS), a climatic relevant trace gas in the atmosp
here. The isolated enzyme, free of other carboxylases, showed a very h
igh affinity towards this substrate. The experiments confirm that CA i
s the key enzyme for the consumption of COS in higher plants. Furtherm
ore, the identification of this enzyme furthers our understanding of a
dditional sinks for COS, which are needed to understand the balance of
known global sources. Copyright (C) 1996 Elsevier Science Ltd
