Abstract
The inhibitory action of various anions on cyanase activity is described and it is shown that halides inhibit the enzyme competitively. The previously reported Kmvalue of cyanase was measured in the presence of NaCl and was therefore erroneous. The molecular weight of a partially purified enzyme was determined by gradient centrifugation in sucrose, but it seems probable that this molecular weight is that of a polymer. The high specificity and the heat stability of cyanase are also described.Keywords
