An amino acid capable of coordinately binding to a metallic complex is introduced to an active site within the enzyme or another controlled position near the active site. Therefore, when a mediator is introduced into the enzyme, a mediator-introduced position is controlled to be held at or near the active site.

An anti-interference determination method for an enzyme electrode biosensor comprises the following steps: constant a and Michaelis constant b are calculated by firstly measuring corresponding currentvalue X of a to-be-tested sample, then measuring corresponding current value Y of the to-be-tested sample and equivalent standard sample and finally measuring corresponding current value Z of the to-be-tested sample and half of the standard sample. Concentration of the to-be-tested sample after compensation is calculated finally, influence of interference factors is eliminated in the determination method, and a determination result obtained with the determination method is more accurate and more reliable under the condition of presence of an interference source.
