Bond Specificity Enzymes that show bond specificity are specific to substrates having similar bonds and structure [1].
WebFeb 18, 2004 · Unfortunately, their high substrate specificity severely limits their applications. Polymerases with tailored substrate repertoires would significantly expand their potential and allow enzymatic synthesis of unnatural polymers for in … WebFeb 26, 2024 · The Specificity Constant. The Michaelis constant KM reflects the affinity of an enzyme for its substrate; kcat reflects the catalytic ability of an enzyme. The ratio of these, kcat/KM, is the specificity constant, which is a measure of how good the enzyme is at its job. A high specificity constant means that a reaction goes fast (kcat is big ...
WebAug 1, 2024 · This study provides high substrate and product specificity of TsCDase. TsCDase is able to prepare higher yield of maltoheptaose through conversion of β-CD in … 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.
WebOct 10, 1994 · A cloned human bilirubin UDP-glucuronosyltransferase (UGT) stably expressed in Chinese hamster V79 cells was used to assess the substrate specificity of the enzyme. The catalytic potential (Vmax/Km(bilirubin) of the enzyme with UDP-glucuronic acid (UDPGA) was 2-fold and 10-fold greater than that for UDP-xylose and UDP-glucose …
