NoteCreated after Tanaka et al. [PMID=38300345] who demonstrated the b-glucosyltransferase activity on b-1,2-glucooligosaccharides of the multimodular protein Thit_1831 in Thermoanaerobacter italicus Ab9, that comprises an N-terminal GT84 and a C-terminal GH94. Family with remote homology to GH144/clan-S, always found in such multimodular architectures.
