The in vitro effect of Al3+ ions on pepsin activity at pH 2, via kinetic parameters was evaluated. Kinetic study showed that Al3+ ions increase the maximal velocity (Vmax) rather than apparent affinity for substrate (KS) implying the non-competitive nature of activation which indicated that aluminium was a non-essential activator of partial non-competitive type.Physical chemistry 2008 : 9th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 24-28 September 200
