Fig. 5From: Characterization of the 4,6-α-glucanotransferase GTFB enzyme of Lactobacillus reuteri 121 isolated from inclusion bodiesFourier Transform Infrared (FT-IR) spectra in the amide I region of different GTFB preparations. Soluble GTFB, refolded GTFB, and ncIB GTFB proteins isolated from E. coli incubated at different temperatures (25 and 30 °C) were analyzed.
