Abstract: Lanthanum chloride can promote expression efficiency of rscu-PA-32k gene in yeast. 2 and 5 mmol·L-1 LaCl3 increase the activities of the expression product by 13% and 20% (from 14.6 to 16.5 and 17.5 U·ml-1). Cerium chloride can decrease the activity of expression product. 2 and 5 mmol·L-1 CeCl3 decreases the activities of the expression product by 21% and 33% (from 14.6 to 11.5 and 9.8 U·ml-1).
