A novel PTS related gene cluster with overlapped gene was found from metagenomic library of termite hindgut.
There was an interaction between the PTS components Glu1392 and Glu1923, and the co-expression of these two components was responsible for the utilization of the glucoside substrates in E. coli.
The glucosidase Glu1392 had a very high tolerance to glucose with a Ki value of 2.25 M.
