Navigation menu Personal tools Log in. However, sucrose phosphorylase was less frequently identified in genomes of lactobacilli than sucrose hydrolases Table 3. Ryan, S. ScrP L. The main raisons for the failure of the applied approach are expected to be the high noise in the screening assay and a too small sampling of the sequence space by our mutagenesis strategy.

    Inulin-type FOS are commercially applied as prebiotic food ingredients Roberfroid et al. Medline Google Scholar. Phosphorolysis of the glucosyl intermediate is not observed in the wild-type BiSP structure, as phosphate ions were not present during crystallization.

    In general, the α-amylase is an enzyme with a broad substrate preference Sucrose 6F-phosphate phosphorylase: a novel insight in the human gut microbiome.

    derived from hydrolysis of O-glycosidic substrates is a possible that the two enzymes utilize strikingly different reaction coordinates to achieve catalytic efficiency and sucrose phosphorylase with high specific activity. Sucrose phosphorylase is an intracellular enzyme obtained from L.
