Reconstruction of ancestral L-amino acid oxidases to broaden substrate selectivity

Conference Dates

September 15-19, 2019


Characteristic functions of enzymes, such as high thermal stability and substrate specificity, are attained during the evolutionary process. Ancestral sequence reconstruction (ASR) is applied to infer the process by designing artificial enzymes which are located on ancestral node of phylogenetic tree; here, the inferred enzymes called ancestral enzymes. Ancestral enzymes often exhibit substrate promiscuity and high thermal stability of which functions are suitable to perform enzyme engineering. In addition, applicability of the ASR is high because the method requires only sequence data to design ancestral enzymes. Thus, we believe that artificial enzymes contributing to progress in enzyme engineering can be designed by ASR.
