The nonpathogenic strain Arthrobacter nicotianae produces two sialidase isoenzymes, NA1 and NA2, with molecular masses of 65 kDa and 54 kDa, respectively, as determined by 10% SDS-polyacrylamide gel electrophoresis. NA1 and NA2 exhibit maximum activities at pH 4 and 5, and both show clear thermal optima at 40 degrees C. They are stable at temperatures up to 50 degrees C.
