This serum was used to evaluate the liver enzyme function through some biochemical parameters such as aspartate aminotransferase (AST), alanine aminotransferase [ 18] alkaline phosphatase [ 19, 20]; creatinine [ 21] and protein [ 22].
Once identified by CPDL, these residues can be targeted for reciprocal switches between the two groups to introduce variability and evaluate their effects on enzyme function.
Thirteen mutant proteins were produced, in order to evaluate the residues role in enzyme function.
Primary aim of this study was to verify potential association between genetic polymorphisms of CYP19A1 and the letrozole activity evaluated by measuring estrone sulfate circulating levels as an index of aromatase enzyme function.
To evaluate the level of agreement of EFICAz predictions with other sources of annotation, we compared our enzyme function assignments to those available in the Genes database of KEGG.

These readily reproducible methods can be used to improve enzyme function by directed evolution, to covalently immobilize enzymes, to microencapsulate enzymes and cells, and to manufacture enzymes for human health, nutrition, and environmental protection.
An additional set of targets was announced consisting of 1,301 enzymes from multiple species and metagenomic studies that were the focus of the Enzyme Function Initiative project51.
Lack of adequate digestive enzyme function, which can come from acid-blocking medication use, or zinc deficiency.
