Popis: Xylose isomerase was purified from a transformedE. coli strain (LE392-pRK248/pTXI-1) (Lastick et al., 1986) that overproduces the enzyme by induction of the strong lambda PL promotor. Kinetic data, N-terminal sequence analysis, SDS polyacrylamide gel electrophoresis, size exclusion chromatography and immunodiffusion were used to compare the overproduced enzyme with xylose isomerase purified from xylose induced, non-transformedE. coli LE392 cells; no differences between these purified enzyme preparations were found.
