[[https://www.uniprot.org/uniprot/BE_THEKO BE_THEKO]] Catalyzes the formation of branch points in alpha-glucans by cleavage of an alpha-1,4 glycosidic bond and subsequent transfer of the cleaved-off oligosaccharide to a new alpha-1,6 position. The branch chain-length distribution of the reaction products shows degree of polymerization (DP) of 5 to 30, with two local maxima at DP 6 and DP 11. Exhibits an alpha-retaining catalytic mechanism. Does not display alpha-galactosidase or pullulanase activity, since melibiose and pullulan are not substrates. Is not able to catalyze the hydrolysis or transglycosylation of maltoheptaose, suggesting that the TK1436 protein contains neither alpha-amylase nor 4-alpha-glucanotransferase activity.<ref>PMID:16885460</ref>
