(i) UTP-glucose-1-phosphate uridylyltransferase (EC 2.7.7.9) sourced from Escherichia coli K-12; and
(ii) UDP-glucosyltransferase sourced from Escherichia coli K-12; and
(iii) sucrose synthase (EC 2.4.1.13) sourced from Escherichia coli K-12;
(f) by enzymatic conversion of purified stevia leaf extract to produce rebaudioside I using both of the following protein engineered enzymes:
(i) UTP-glucose-1-phosphate uridylyltransferase (EC 2.7.7.9) sourced from Escherichia coli K-12; and
(ii) sucrose synthase (EC 2.4.1.13) sourced from Escherichia coli K-12.
