-
activity is induced during growth with cyanide or cyanate, but not with ammonium or nitrate as the nitrogen source
-
-
?
additional information
?
-
no activity in cells grown with ammonium, nitrate, arginine or ornithine as N sources, cyanase of this strain has an assimilatory role but is not essential for cyanide assimilation

?
additional information
?
-
cyanate is not a key intermediate in the degradation of cyanide, since the cynS mutant is still able to use cyanide as the sole nitrogen source
