Engineering and kinetic characterisation of two glucosyltransferases from Arabidopsis thaliana.

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 Km towards the acceptor scopoletin.
