2.3.1.110 | F145Y | KM-value for tyramine is 2.3fold lower than wild-type value, Vmax is 3fold lower than wild-type value. Wild-type enzyme shows no activity with serotonin, mutant enzyms shows activity with serotonin | Capsicum annuum |
2.3.1.110 | F145Y/Y147F | KM-value for tyramine is 2.3fold lower than wild-type value, Vmax is 4.2fold lower than wild-type value. Wild-type enzyme shows no activity with serotonin, mutant enzyms shows activity with serotonin | Capsicum annuum |
2.3.1.110 | additional information | a series of chimeric genes is constructed by reciprocal exchange of DNA segments between the serotonin N-hydroxycinnamoyltransferase and tyramine N-hydroxycinnamoyltransferase cDNAs. Functional characterization of the recombinant chimeric proteins revealed that the amino acid residues 129 to 165 of serotonin N-hydroxycinnamoyltransferase and the corresponding residues 125 to 160 in tyramine N-hydroxycinnamoyltransferase are critical structural determinants for amine substrate specificity | Capsicum annuum |
