"an investigation was carried out regarding the inhibitory effects caused by various metal ions (Fe(2+) Pb(2+) Cd(2+) Ag(+) and Zn(2+) ) on G6PD enzyme activities as per Beutler method at 340 nm under in vitro conditions. Lineweaver-Burk diagrams were used for estimation of the IC50 and Ki values for the metals. Ki values for Pb(+2) Cd(+2) Ag(+) and Zn(+2) were 113.3 215.2 19.4 and 474.7 muM respectiv..."xsd:string
