High substrate specificity

WebOct 26, 2024 · This specificity is a molecule recognition mechanism and it operates through the conformational and structural complementarity between the enzyme and substrate. 1. Bond Specificity Enzymes that show bond specificity are specific to substrates having similar bonds and structure [1]. In the field of biochemistry, the specificity constant (also called kinetic efficiency or ), is a measure of how efficiently an enzyme converts substrates into products. A comparison of specificity constants can also be used as a measure of the preference of an enzyme for different substrates (i.e., substrate specificity). The higher the specificity constant, the more the enzyme "prefers" that substrate.
