Description
Description
MW = 29.1 kDa. Full length Carbonic Anhydrase II (Carbonate dehydratase II, Carbonic anhydrase C) cloned from human cDNA and expressed in E.coli. The protein consist of the human Carbonic Anhydrase II with a mutation Ser2Ala. (Swiss prot accession: P00918). Mass spectrometry (MALDI) showed that the first aminoacid (Met) is processed during the expression.
