This study describes the characterisation of a chimeric mutant derived from two arabidopsis glucosyltransferases, 71C1 and 71C3. A chimera, N1C3, was constructed to contain the N-terminal domain of 71C1 and the C-terminal domain of 71C3. The chimera and the wild-type GTs displayed a similar K-m towards the acceptor scopoletin. However, N1C3 had a K-m near identical to 71C3 towards UDP-glucose, but was three-fold lower than that of 71C1. The results suggest that the acceptor and sugar donor are recognised independently by the N- and C-terminal domain of the GTs respectively, and provide a foundation for the future design of glucosyltransferase biocatalysts through assembling domains with different affinity towards the acceptor and donor.
