sucrose + maltose | alternansucrase acceptor products from maltose do not contain dextran-type linkage sequences. Instead, the product series is comprised of an alternan-type linkage sequence, with some pairs of consecutive alpha-(1,6) linkages in the evennumbered members of the series. The distribution and sequence of linkages is apparently kinetically controlled. Branch formation is not detected below DP 8. Alternansucrase forms alpha-(1,3) linkages only when the acceptor is a-(1,6)-linked, thereby prohibiting the formation of sequences of alpha-(1,3) linkages. Furthermore, the enzyme appears not to make products containing more than two sequential alpha-(1,6) linkages, thereby prohibiting the formation of dextran-like linkage sequences | Leuconostoc mesenteroides | ? | - |
