摘要The tobacco RuBPcase was purified by the method of ( NH4) 2SO4 precipitation and Sephadex G-200 column chromatography. The effects of Ln(3+) on inhibition of RuBPcase activity were studied. The results show that the v(max)(maximum velocity) of RuBPease does not change, but its k(m) (Michaelis constant) increases with a k(i) (inhibitor constant) when increasing the concentration of Ln(3+) in enzymatic reaction. It indicates that the inhibitory action of Ln(3+) on tobacco RuBPcase is a model of competitive inhibition with Mg2+. The k(i) of La3+, Ce3+ and Gd3+ is 26.3, 34.3 and 200 mumol . L-1 respectively. Their inhibitory action on the RuBPease is in the order of La3+ > Ce3+ >> Gd3+.
